Thread Starter 
I am new to the site, but i have been trolling the site for a long time now lol but decided to join cause i cant seem to get my E8400 to 4.0ghz, i tried the overclocking tutorial on here for it and i think i did something wrong, not sure. I run Prime95 and about 3 hours in it will freeze. I don't think cooling is an issue, CPU doesn't get over 68C with prime, Idles at 41C. here is what i have

System Clocks

CPU multi - 9X
PCIe x16_3 - 100mhz
SPP<->MCP ref clock - 200
HT multi - 5X (all)
HT spread - Disabled
PCIe spread - Disabled
SATA spread - Disabled

FSB Memory Config

SLI-Ready Memory - Expert
FSB Clock Mode - Unlinked
FSB mhz - 1800
MEM mhz - 800mhz

Memory timing - Optimal

Intel Step speed - Disabled
CPU thermal control - Disabled
C1E enhanced halt state - Disabled
Execute Disable bit - Enabled
Visualization Tech - Disabled

CPU core

1 - Enabled
2 - Disabled
3 - Disabled

System Voltages

(probably where i screwed up lol)
CPU Core - 1.39375V
CPU FSB - 1.3V
Memory - 2.100V
Nforce SSP - 1.40V
Nforce MCP - 1.60V
HT nforce - Auto


Compute Specs
CPU - E8400

PSU - Diablotek 675 UL series
CPU cooling - Silverstone nitrogen
Memory - OCZ SLI ready DDR2 800mhz - OCZ2N800SR4GK
GPU - MSI Radeon HD 5770 Hawk
Case - Old Thermaltak armor Full tower.

I had an E8400 @ 4.0 GHz on an EVGA 680i SLI.  There are more options in your BIOS, but still I think the only change I can see so far is taking the CPU FSB up to 1.4V.

 

If that doesn't work, then maybe take the SSP to 1.45V.

 

If that doesn't work, then it may be the PSU because the PSU can be the culprit - especially if it's not delivering clean and stable power (and this one may be delivering the opposite of that thereby possibly making it impossible to stabilize 4GHz).

 

However, what core voltage are you seeing in CPU-Z when Prime95 is running?  It may still be too low yet.

It's like advanced alien technology! :)

It says exacly what my bios says for voltage. I will do that now and see how it does while im at work. I will update if i get back and its frozen lol.

Thanks for the pointers thumb.gif

I was just saying that in your original post, I see things that I didn't have in the EVGA 680i SLI's BIOS.

Oh ok, yea the 780I is really nice i gotta say. I am gonna replace the damn SB and NB ASAP that blowing hot air on my GPU is not cool.

Also it didnt like the 1800 FSB, so i set it to 1783 and it booted just fine, Its running threw prime95 at home. Having the gf check it every few hours to make sure it didnt freeze. I hope this works. I really would like it to be 4.0ghz lol.

I was actually thinking of getting a new cooler.

whatcha think of

Yeah, these nForce boards are like space heaters!

 

I had to use 1778 MHz to get 4 GHz.  If I tried even 1780, then the board was like, "I don't think so, Tim!" (and my name is Tim, so that was kind of weird).

 

What are you using now for CPU cooling?

 

The 212 Plus is pretty nice.  I don't know what's good or bad for fans so I can't judge those, but I've heard good things about the 212 Plus!  As long as you fill those gaps with thermal paste that are in between the exposed pipes before you apply the thermal paste normally, it should be very good.

Yea it was like "hell no 1800 will not work ace, We are in safe mode now" lol

I am using this

http://www.newegg.com/Product/Product.aspx?Item=N82E16835220033

With a silverstone high cfm. they don't make that fan anymore frown.gif. The scyths are pretty good fans, a friend of mine has 2 of them and the push a lot of air. I have a fan controler so if im watching a movie i can turn all these fans down, and just about every one of my fans is wired directly into a power socket. Not the psu. Less strain on the PSU for the 6 fans i have lol.

What do you mean by the gaps?

Well, it certainly looks kind of cool - and it's very low profile.  It must not be that bad if your max temp is only about 68.  I would expect worse from something this small!  That must be one awesome fan that's on it. lol  :)

They go a bit far and recommend lapping it, but I think that's just a bit extreme. lol  Sure it would help, but come on.  :)

you ever try putting a rad box on, a hollowed out 120mm in between the fan the cooler? also check this awesome thread out. . .
