Trying to OC C2D w/ GA-P35-DS3R Mobo

[theguy82]

Hi,

I just got a P35-DS3R mobo a few weeks ago. I decided to try to OC my CPU again. I had an Abit AB9 mobo before. I found the abit one a lot easier to OC as far as just changing certain settings. With this new mobo, I find the settings a little bit harder to understand. I am not an experienced "OCer" by any means.

I read through forums and the guide on this site and still unsure on what settings I need to change. It said to make a ratio of 1:1 with the FSB:RAM or whatever. I don't see this option in the bios.

Anyways, I am just wondering if someone who also has this mobo could help me out a bit.

My specs:

Intel C2D 2.13 E6400 (Stock Fan)
GA-P35-DS3R Motherboard
2 GB of Kingston Generic RAM PC-5300
BFG 7900GT 256MB Video

With the previous mobo I got the CPU oc'd to about 2.88ghz on stock.

Please help someone

Go onto the BIOS screen and hit CTRL+F1, this should bring up additional menus. If it's not in there, get out your manual and find it. I have an older Gigabyte (i865 on the old Computer..) and I just checked it. Ram is under "Frequency/Voltage Control" and is then under "Memory Frequency For." My options are 1.33, 1.66, and 2.0.

Yours could be different. I don't know for sure where it is on the P35 Mobo, however, I'm sure someone here does.

This is weird. I don't get this motherboard at all. I went in again trying to figure this out. I changed the default CPU Host Frequency from 333 to 340 or 345. For the mem multiplier, there was no 1:1 ratio, so just to see it, I put it to 2. When I booted up into windows my CPU now shows 2.84ghz. I don't see how changing the CPU frequency would bump it up that high.

I've ran my cpu on this speed before, so I am not worried, but I just don't get how it came up with that number :/

345 X 8 = 2760 MHz.

You sure you didn't maybe put in 355? I ask that because 2.84 GHz through your multiplier is exactly 355.

 

[theguy82]

I just don't get it though. The default is 333. When I boot into windows, I have the default of 2.13ghz. I push it up to 345 in the bios and when I boot up it shows 2.84ghz with a multiplier of like 473x6 (so Core Temp says).

I ran through prime95 for a while and it was stable. I didn't see my temps go higher then about 65c. I like what it is at now, but I am just wondering the reasoning behind all of this :/ My old mobo was much more straight forward.

Check it with CPU-Z. Windows doesn't read it right and Core Temp looks at windows. My Core Temp reads 450x9 on mine. CPU-Z reads it right at 400x8.

 

[theguy82]

This is very interesting. Annoying really. I got CPUZ and it shows 2.84, then I opened it again and it is showing 2.13 again (355x6). I just don't get this motherboard and it's bios at all.

Disable C1E and EIST in the BIOS to correct the throttling.

 

[theguy82]

I disabled C1E, but I don't have EIST option in my bios. I still have stuff showing up as 2.13. Well cpuz shows up as 2.13 and core temp shows up as 2.8.
Thnx for the replies btw.
