Helping a Friend OC GA-P35-DS3L

[BALISTX]

Well as some of you may know I sold my old E2180 rig to a friend at work. Now comes the time for us to OC it. Currently he is running at stock. I have a theory that I want to run past those how have more experiencing OCing the Gigabyte GA-P345-DS3L motherboard.

Before I get into my theory here is the system specs.

Intel E2180 (M0 stepping)
Gigabyte GA-P35-DS3L (rev 2 I think) BIOS will be flashed to F8a
4GB of Mushkiin HP2-6400 4-4-4-12
XFX GeForce 7900 GS XT (Upgrading to an 8800GT 512MB)
CPU HSF AC7 Pro

Here is my theory. We want to keep the memory as close to running at 800MHz as possible and his goal is a modest 2.6-2.7 OC (Which I achieved 2.75 - 275x10) What i want to do is try 400x7=2.7GHz and I know from seeing other people and other reviews that this board can run a FSB of 400MHz. With that being said. We can then set the Memory multi to 2 and that will give us a memory freq of 800MHz.

Does my theory sound like it will work?
If so will the AC7 be enough to cool the CPU
Will I have to up the vcore?
Will I have to up the NB voltage?
We will try and cool the NB with a 40mm fan.
Currently there are 3x120mm and 1x80mm fan in the case.

Just checking something isnt 400x7=2.8ghz ?

• Your Theory: looking good.
• AC7: yes, more than enough. As always, keep an eye on the temps.
• Vcore: maybe, but not by much.
• VFSB: + 0.1V probably.
• NB block: definitely cool that NB.

400MHz x 7 is 2.8GHz, which can be done rather easily with the setup, and the 2x Ram multi from the new F8a BIOS will surely help. And remember that your HP2 can run upto 500MHz.

Have fun!

edit: I forgot to add that I built a rig last Monday with an E2140, 2x1Gb OCZ Gold, Gigabyte G31-S2, AC7 and a Coolermaster 650W. 2.8GHz was easily reached w/1.35V VCore (vid was 1.33). That was just before having issues with the onboard video and some artifacts popping up...

John, thanks for the info. I was pretty sure that would work. We will give this a shot on Monday. How much do you think the vcore will be need to upped? The current vcore I believe is 1.20 or 1.25, so maybe up it to 1.30?

Yes and 400x7 is 2.8. It was 3am when I wrote that and I was tired LOL.

The E2140 that I installed had a rather high Vid of 1.33. At stock, 2.6GHz was reached and tested as stable with 2 hours OCCT. 2.8GHz needed 1.35V (up by 2 settings in the BIOS) to be stable 2 hours OCCT. I didn't need more testing since this rig will be mainly used for surfing and using the Office Suite.

Not a bad OC. I want to get another DS3L board with a E8400 and a set of 4GB Mushkin XP Redline PC-8000. My goal is 500FSB x 8 = 4.0GHz and setting the mem multi to 2 to get 1000. I know I could a set of HP2-6400 and push them to run at 500 like you said earlier but I'm not a huge fan of pushing memory. What do you think.
Cooling wise I doubt an AC7 would be sufficient enough to cool the CPU.

[3.0charlie]

Actually the oc was limited by artifacts from the onboard video... that chip could have gone faster.

As for your E8400-DS3L combo using the AC7, I don't know. I haven't played with the E8400 to compare its heat output. The AC7 is a great little HSF, but it has its limits. Ram-wise, using the 6400 is the luck of the draw. But you'll need some hefty voltage for 500MHz - 2.2, 2.3V. That's why I'm shopping for some PC2-8500...

On second thought instead of buying new ram, I could atempt this: FSB 450x9 wich would run my CPU at 4.0GHz and my mem at 900 using the 2 mem multi. John, do you think those EM-6400 can handle 450MHz?

Yes Sir, they can.

Sweet, I can save some coin. What was vdimm set to with the EM's? Did you put any additional cooling. I think my case will be sufficient enough cooling. I will have 6x120mm fans. I can then take that extra money and get a TRUE 120.
