I'm gonna get my hands on a 940 or better as soon as I can afford to, but right now things are really tight...

The 50 mhz more you've gotten over mine is a HUGE upscale. Well not really. If perhaps the SB750 was out when the 9850's where introduced, which I was the first in this forum to own and post at time of release, I would probably have bought that board.

But this board has done great for over a year and is still getting me high clocks.

To bad you haven't gotten your hands on a Phenom II x4 940 yet. I'd really be interested in seeing some awesome clock speeds.

10% over the 4100mhz I have should put you around 4.55ghz. For that clock speed I hope you invest in some cooling as well

Additional Comment:

I also just rated this Thread bringing it back up to 5 star status. Cheers!!!

LOL the 940 IS COMING SOON!!!!!!!!!! Need to make some money!! Can you help me overclock my bank account????? Maybe by the time I get it in a month or 2 price may be $200.... LOL. BTW, I was gonna get a new case and maybe a new PSU not that I need a new PSU(700W) but I love the cable management on the new "PLUG IN" PSU's. Why get a pretty new case and the old floppy arse cable everywhere PSU.

I believe 3.3GHz on the 9950 can be done. I run 3.25GHz( I can load windows on 3.3+ but unstable) on 9850 although I am liquid cooled but this thermaltake bigwater kinda sux. A decent air cooler will be able to get my temps easily, im low 40's idle and high 40's-50'ish fullload at 1.45V. That's kinda silly on the liquid cooled. depends on the quality of air cooling.

Just got the Phenom 2 940 today, formatting and reinstalling my comp due to slow loads, just downloading 3dmark 06 and i am gonna do a stock run to see what my base mark is i will let you all know how i goes.

I have 3.3GHz stable on my 9950 at 1.45v on air cooling with very low temps

[cstmcomps]

You should be able to get 3.3 stable at 1.45ish volts. What problems were you getting at that speed? Did you try lowering the voltage a notch to see if it would stabilize?

Hey man! All I gotta say is Wow to your Ram speeds. Yea the one in your sig there. I had to take a double take at that one.

I'd also like to learn a bunch about how your getting those clock speeds man. That's crazy. I can get 1200ish on air. I believe more is in there. Muskin 1067 5-7-7-24 stock timings.

Oh I gotta know what voltage your running for that also. I don't like going crazy with Ram voltage personally.

[cstmcomps]

2.3 volts... 5-5-5-15-20 timings... done with FSB increase... and they're liquid cooled, they stay right around 32-35C even when loaded...

Guess you don't need a AM3 board and ddr3 any time soon lol.

[cstmcomps]

LOL... no I guess not... I have heard of some people hitting 1600Mhz with this RAM, but it would overheat on them... so HA! on them, mine doesn't even think about getting warm let alone overheating!

[rukik]

These Phenom II 940 rock! got it up to 3.6 Ghz stable at 1.4 V didn't breach 43 C in prime stress test on air! I turned the processor down to 3.3 and the voltage down to 1.375 to drop temps even further, and also i noticed that the cup was twiddeling its thumbs so to speak while i was gameing, no need to run it at 3.6.

BIOS 1.5 FSB 200, Multiplier 16x (3.2Ghz) CPU volt 1.33, HT ratio 10x, Memory Dual channel (ganged 128bit) ratio 1:2.66 (=1066) 2.1volt set to 5-5-5-15-21-2T and 127ns, memory hole enabled.
Disabled the TLB setting and auto overclock.
The system run stable @ 3.2Ghz for 3dmark06 and game, but cannot do AOD stability test. I haven't tried other stability programs though. Just start using 9950 last night. before, I used 9750.
Any idea how to increase beyond 3.2Ghz without decreasing memory speed? I can't increase FSB when Multiplier on 16x, it only POST but window won't start.

I am stuck with a ram issue(You may have the same) . A good way to find out is if it may be Ram is to run a stress test with Prime95. Run it full. If it does not pass, run it with Ram not being tested(Small FFT's) and then run it In place of Large FFT's(There are 3 choices in Prime95).

I was getting errors with full FFT's and felt I was at my max pain. I then tested it with the 2 other choices in Prime95. With some Ram tested and In place of full FFT's(second choice) I passed both.

I then tried and passed at 3.3GHz with a 9850BE with Ram turned down to 667 and with OC it was overclocked at appr. 780MHz.

Next, I tried 800Mhz. With the OC, I did not pass Prime95. I knew 667 was the proper setting for my Corsair XMS at this overclock. I then raised the FSB a bit and got a no go.

Currently, I am running 4G Corsair XMS which is fairly decent Ram. Even if I cannot get my OC higher, I know without a doubt I can get better performance with Corsair Dominator Ram(which you have) and is supposed to be real good ram(1067MHz). I feel I can get close or hit the 17,000 mark in 3DMark06. Also I feel 3.35Ghz or possibly more(Stable) is achievable. I will get the Ram tomorrow and let you know how much more OC(If any) or if I get and if I achieve higher 3DMark06 score. If I do not pass Prime95. I will play with Ram at 1066,800,667 and 400MHz to see what gives. If your interested we can compare notes. I do have a Teamspeak server which will make it quicker.

The point I am trying to make is maybe you need to back down the MHz of the Ram to pass stress test at your overclock. A necessary evil. Once you do this, you may be able to overclock more GHz and then your CPU performance and 3dMark06 score will increase back up again. Sacrifice MHz in Ram to get more GHz in CPU. I am at the point of trying the trade off each to see if I can OC even higher with testing CPU performance if this makes sense.

Try different MHz(800,667,400). Run the stress test(Prime95) at each level. If you pass with less ram tested(Prime95), you need to back it down(Ram). Start at 1067 then 800 and so on. I think this testing (less ram tested) and you pass,You may see the culprit. It may be the Ram settings(Mhz). Once you find the pass point slowly add FSB.

Another thing you may try which definitely will lead to higher 3DMark scores, is use a lower multiplier and higher FSB speed. This will give you higher Northbridge and higher Hypertransport. This will increase your CPU performance and 3Dmark scores. Try 15x with FSB of 213 or 214 (3.2GHz). Next run a 3Dmark test and see what score is. You will be surprised. The result is same overclock with increased performance. I am getting better at this and learned a lot in the past weeks. Now with the lower multiplier and higher FSB, Your Ram MHz will increase probably leading to more instability. This is an endless cycle until you find the "Sweet Spot".


You are doing good with your mobo but it does feature the SB600 chipset. It seems by threads I have read, the SB750 chipset is easier to overclock and better for the original Phenoms. Shrimp denies this and he is an all-star, but I had a SB600 MOBO and I have overclocked about 12% better with a mobo featuring SB750. It is supposed to be better technology and run a bit more efficient. I made an excel spread sheet with specs and they are really spec'd about the same but SB750 features ACC and all reviews and pro testers say this allows about 10% better overclocking. By my stats, that is about on the head.

Your video card. I had the same card with 9850/ M3A32-MVP DELUXE(Shrimps board)/3870. I was benchmarking about the same as you at 3.0GHz(Around 12,000 points). Lower Multi and increase FSB and the score will increase. I threw in another 3870 crossfire and I benchmarked 15,000+. See next screen shot.




Here is my results featuring 9850/M3A78-T/GTX280



Now, I was unstable at these settings(Passed 3DMark06) with the Corsair XMS 800MHz had Meemory down to 667MHz(Oc'd to appr 790MHz). Again we will see what the 1067 Dominator does at 1066 and even turned down to 800 Which should be about 1000MHz after OC'ing. If my theory works at 3.33GHz CPU and Memory at 1000MHz, I will add 210MHz to my ram giving me better performance at the same OC. I can then take my FSB up slowly to see if I can achieve a even a higher overclock.


Good luck Death

You gotta use the thumbnails man. Admin strongly urge this. When you hit reply to a post, it's the little paper clip looking thingy. Click it and upload from your PC or PhotBucket. It will make your posts look cleaner and also prevent you from getting an infraction. Just a heads up!

[jbaranski111]

will do had no idea.

LOL Thanks.

jbaranski111... you may want to change your avatar and message as those could get you an infraction too... we don't want to see you get banned cause that would suck...

[Jamar16]

got my 9950 up to 3.4ghz at 1.48v validation still doing some tweaking to enhance stability

[cstmcomps]

Awesome! It's hard to get that stable, but if you do please let me know how.

Add another to the 3.3 Ghz club


Running a DFI LP JR 790GX-M2Rs, 200x16.5 on just 1.38 V, NB set to 1.30, everything else auto.

It's been running stable for weeks on 3.3, very heavy stressing. Sensor snapshot shown running F@H for six hours, with ambient temp of 78 F ( 25.5 C ) The temps do get a little high, but the ambient temperature is mostly to blame for that it's usually about 75-80 F in my room ( 24-26 C). The highest I've seen so far is 58 C.

I've got it to POST and benchmark under 3.4 Ghz, but it is not stable. I've bumped the vcore up to 1.45 without it running stable, but at that point the temperatures were too high for my liking.

I'm running a CoolerMaster HyperCooler 212, which is a mammoth of a heatsink with a 120 MM fan. It has the room to mount an extra, so I may purcahse that and try to get up to 3.4 later.

Anyone know why /proc/cpuinfo insists on reporting it as 3299? I mean, the 1 Mhz doesn't really count, but still... I can't help but feel it makes it a little less legitimate.

[cstmcomps]

Great numbers especially on air! The CPU may show a slightly different speed than you set in the BIOS because what you set in the BIOS is just a rough number. For instance, currently I am running at 3.35Ghz at 210x16. It actually downclocks slightly to 209.1x16. I don't know why, but instead of running at 3360Mhz it runs at 3345.6Mhz. The difference is so slight that it only accounts for three 3D Mark points. That's not enough for me to worry about.

[chartiet]

I am waiting for my pc but am learning overclocking for the first time in the meantime.

I have;
Phenom II X4 9850 B.E. (2.5GHz/125W) B3
AMD 790X
ATI Radeon 4870 1024MB
6GB (2x2GB+2x1GB) DDR2 SDRAM @ 800MHz PC2-6400
Zalman 9700 NT110mm
Vista 64bit

I am not an overlocker, just want to clock to 2.8Ghz.

From all Ive read here, all i ned to do is simply the following.

FSB = 200
14x
1.3v

Ungang memory
disable AMD cool and quiet
enable software mem hole

I will have to use AMD Overdrive since BIOS setting are not availible.

Timing changes to be more stable, but, also told to play with multiplier before FSB.

Question is, do I need to do anything else or can I just set to 14x, keep memeory settings the same, play with voltage if needed and be fine.

I dont want to crate bottlenecks but also want to keep this as simple and stable as possible.

If there are suggestions or spelled out guides for this, please let me know. If not, I appreciate your suggestions.

I am new to this, so please bare with me.

Additional Comment:

How would I go about getting RAM to 1066 if needed. HT mult? Timings?

Is there an equation to calc?
