**Official e8400/e8500 Retail OC Thread

[unclewebb]

Real Temp 1.0 has been released which properly supports these new E8000 processors. I've started a new thread over here:

Comments and general abuse for telling people that their cores are not running as hot as they think they are, are sort of welcome.

Good job!

[Spyrus]

thx Spyrus
i have some issues with my mobo P5k Green... it is degraded...
i cannot be stable at 500 fsb... crap...
I also cannot give more than 1.5 volt on the northbridge... when i put more no boot...
so i am trying at 4410 mhz with 1.37-1.38 but i cannot make it stable...
the same issues i have also at 4000 mhz... it is not stable know...
but at 445x9 it runs at the same volts... 1.2...
so until i will find a desend mobo i cannot search for higher stable frequency...

I do not think there is a degration with mobo! That is a surprise to me!
If you want stable OC,vcore and high fsb Abit can do the job, but you know
the drawback with memories.P5k though can do high fsb (vanilla for sure but
i thing the green is no difference)

there had been degradation reports of p965 mobos in the past.

it's something that can happen BUT it's a bit difficult to achieve

[DemonEyez]

I just post'd at Overclockers about this, but I have found with my board, that 63/63/67 works best for me.

For me setting GTL to 61/61/57 allows me to run 4.2GHz Orthos 8 hours straight

Nice job DemonEyez!!

[DemonEyez]

Thanx! I'm quite happy with it

man, its true... it must be that...
i put 1.7 volt at northbridge, and no boot...
it should at least post, but nothing...
so i think is the mobo...

Have you tried lowering vdimm to as low as you can go rather than safe?

I used to have an Commando that did the same thing untill I lowered vdimm

[ArCElM]

hmm weird, I can do 4.1Ghz at 3.12v but 4.2 seems so hard to get stable without a large jump in vcore, which is annoying.

[mrcape]

Hmm, I think you could try 8.5x and a smaller jump in vcore, and see what it can do at 4.2. I have better luck keeping voltage low with 8.5x495 and setting gtls to 59.59.59. It's worth a try.

Hmm thats a bit beyond my basic knowledge, I don't understand GTL at all, and I have an Abit IP35-E which just gives me a few options for CPU GTLREF

[mrcape]

It's not that much to tweak. What are the options?

[Big Lar]

If it's anything like my board, you only have 57/61/63 and 67 for the CPU GTL's. NB GTL's are only 61/67. I think his board may be the same, not sure tho. Kinda lame to only have those options, perhaps in time with newer bios's....

my vdimm is as low as it gets..
so it is not that...
i put another bios 805 and now it goes 525fsb...
i think is not good for this mobo... most of them hit 560 at least...
mine is also pencil moded...

Hmm I see, to start with, I'd try the 61s for each.

ArCElM was looking for help with the GTL's, I got mine worked out for this clock anyhow, 63/63/67. I am completely stable there and not with other combo's.

Larry

[mrcape]

Yes, I meant that suggestion for him. I suppose it can vary from bios to bios. What's your multiplier and FSB termination setting Big Lar?

Reason I ask is that I was able to get stable at 4.2 - 4.25 using less voltage with 8x and 8.5x and setting gtls manually to about 59, than I could with 9x and gtls a little higher.

My current 24/7 is 8.5 x 500 with 1.3vcore. Similar to yours, but for my setup, I'd need a little more juice at 9x.

[Big Lar]

I'm at 9x470 right now. VTT is still 1.1v, and NB is 1.35v.
I'm waiting on a better bios to come out, I have run both of the newer 1's for this board, but they are both flakey with 8.5 or 8x multipliers with higher fsb. The original bios is the 1 I am running right now, it is the most stable for me, but does not have the option for 1/2 multi's like the newer 1's do. I am patient...

Larry

[mk-ultra]

i have a noob question

gtls, do i set them higher or lower to clock more?

[flesheatinvirus]

I run my CPU and NB GTL ref at .59 and.61 on my P5K prem which helps with high fsb.

I have a p5k prem, what do all those options mean exactly? I'm not really pushing this quad because I dunno where to start lol. I came from nforce4 and things were much simpler back then.

@hersounds: nice! how much vCore & VTT are you pumping it in?

[hersounds]

VTT 1.50 Vcore and e8400 at 1.71, much i know but stable and very cold
only 49 c in core 0 and core 1.
with more time i will post more images and benchs.
