fsb will change your ram speed. why don't you have access to the bios?

Long story which will open up whole can of worms related to other threads.

- Dell.

Additional Comment:

How is Ram speed calc'ed. The ratio of FSB:RAM? What is that? What says I have 800 or 1066?

ok. ram is ( (fsb * 2) * 2)

for 1066 you need you bus around 266 unless your drop your divider. You might need to loosen your timings as well. you can use cpu-z to check your ram speed.

for ocing via software please refer to ShrimpBrimes thread:

Duh on my end, thanks. One last thing, I have read it is a must to change HT multiplier to 4x. What is HT multiplier? What would that do? What is stock? I read through that section and didn't seem to jump out.

Also, in that thread. It seem there is a lot of 940 info and general references to Phenom II's. Do the general references contained in the timing section apply to all speeds of Phenom II's?

Additional Comment:

HT of 4x200 FSB = 800
HT of 10x200 FSB = 2000

Think I got it. Would it be best to just keep RAM @ 800? There is a lot out there about adjusting this stuff.

As for the ram it depends on the ram. Some people drop it to 667 to get a higher fsb if their ram is holding them back. unfortunately it isn't limitless.

HT should be anywhere from 1800-2100 under or over creates the need for cmos resets. I imagine that would be a pita on a dell.

[chartiet]

Are you suggesting that I raise my RAM to 1800 - 2100 or just using an example.

If I go up to 2.8 or 3.0, will my RAM hold me back? How will I know if its the RAM and not something else? Thanks

I was referring to your ht link.

I don't know what ram you have.

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

Do you need to know more specifics?

[UNIXgod]

might be able to get your ram to 900. 1066 might be a stretch with all slots filled.

This might be a head smacker, if I wanted to go to 900, would that be advantageous, worth it, stable? What would I adjust and to what value to get 900? Is there any benefit to buying another stick of 2gb ram and getting 6gb @ 3x2gb? Again, I would want a net stable overclock of 2.8 to 3.0 max. Does ram play a large role in that? Or is it the two worlds that you can oc separately to get max speed? Eventually, ill max the thing out at 8gb. I Appreciate your thoughts.

you drop your ram to 667 and change your bus frequency. this will oc your chip and give your ram some room to hit it's limit.

I don't follow. Sorry.

It's a bios setting. since your not using the bios it would be best to read ShrimpBrimes thread. Just one thread down with a ton of info on software based ocing.

[chartiet]

Update:
Size = 6144MB
NB Freq = 2000MHz
DRAM Freq = 400MHz
FSB/RAM = 1:2

BIOS = 1.0.2
L2 Cache = 2048KB
L3 Cache = 2MB
Mem Installed = 6144MB
DDR2 SDRAM

I can access BIOS and adjust all the usual overclocking settings, no restrictions. YEAH!!

The following settings are available to adjust. All are set to AUTO unless listed otherwise.
Processor Frequency Multiplier
Mem Clock Mode
DRAM Timing Mode
CPU/HT Ref Clock = 200Mhz
Chipset Ref Clock = 100Mhz
PCIE Ref Clock = 100Mhz
Over Voltage
Overclocked DIMM Config

Which mobo?

Nada.

[chartiet]

Here is my info

[UNIXgod]

foxconn's everyones oem. the xps gives your fsb and multi control?

I don't exactly understand the question. From the looks of it, it can overclock just like any other aftermarket mobo and cpu.

Im going to try a BIOS 2.8 w/ 200x14. Shouldnt need any voltage. See if it works. If there is also benefit in adjusting the RAM, I would like to do that as well.

Funny, I bought a Zalman 9700 and the mounting holes on the OEM mobo for the bracket are rectangular spaced while the Zalman brackets are square spaced. The thing won't fit and I must return. There goes my good cooling. It has a fairly elaborate heatsink/fan stock, but idles right under 50c and seen it as high as 55c already without oc.

[UNIXgod]

Those temps are high. I guess I wasn't really asking a question. It was more like I didn't realize the xps gave you such control in your bios. I think that is great for you chartiet. Foxconn is also the oem for asus and gigbyte and the rest. They even make ipods for apple.

Get your cooling under control and post some awesome screenies. I own a dell server and laptop. I understand their quality from the midrange up. I imagine the xps is decent. It is their gaming line non the less.
