E8500 E0 and p5b deluxe match made in heaven

[Jizzzared]

Hi all,
Haven't posted in a while, but I got a new E8500 E0 and was very impressed with what my old p5b deluxe rev 1 was capable of with this new cpu. I previously had an E6400 b2 that topped out at 3500mhz with a max fsb of approximately 490. I can go up to 515 on my motherboard with this new cpu. I was under the impression that I needed an E8500 over an E8400 because I thought my board's fsb would be limited to much lower.

Anyway, I am running this E8500 right now at 4.35ghz. It passed both prime (12 hours) and 40 passes of Intel Burn Test with 1.328 vcore under load (according to cpuz.) I didn't take screenshots at 4.35ghz, but I have one of prime running for 5+ hours at 4.3ghz with 1.32 volts and just for fun I booted up at 4818mhz and completed a pi run. At 4.35ghz on my e8500 compared to 3.5ghz on my e6400, the fps I get in L4D and especially CSS (I often play death matches and in 32 person servers, where my e6400 sometimes struggled to get 60fps at 1680x1050 with everything maxed) is far superior. I was hoping source games would improve and they have drastically.

So basically, if anyone's got this old motherboard lying around and was wondering if it could oc the new dual cores to ridiculous levels, the answer is yes!

By the way, this is all on a Thermalright Ultra 120 (non-extreme)

Not bad at all Looks like you got some really nice results from that chip.

Bravo! My ballistix come back tomorrow morning I'll try for 5ghz myself when they come in.

The old P965 chipset was a BEAST. I wish my old DS3 v1 could support 45nm...

 

[Jizzzared]

Thanks guys, I thought the chip was pretty nice myself.

Rainless, I tried for 5ghz with 1.575 vcore, but it was a no go and I wasn't about to put anymore vcore for a mere screenshot. Surprisingly, the highest I could boot into windows (I didn't try for very long though) was 4818 and I was able to complete a 1m pi calculation. With past cpus, the highest I could boot into windows was nowhere near stable enough to do a 1m pi calculation, which is interesting. As for P965 being beastly with the newer dual cores, I learned that first hand. I feel I have definitely maxed this cpu and find it hard to believe that any newer chipset (including P45) would be able to take this E8500 any higher (although it might be able to get higher fsb with a lower multi.) Long live the P965!

Coukd you post some detailed bios settings for me. I have the same setup.

Rick James are you on a P5b deluxe? Some of those Bios settings do not look familiar to me, but I guess it could be a different bios than I'm using.

Moomaster, The most important settings for my overclock were as followers:
fsb termination 1.2v (any higher will not boot for me)
northbridge voltage 1.45v
vdimm 1.9 (i'm using loose 555 timings, though)
vcore 1.3875 (Bios voltage, in cpuz under load it turns out to be 1.328)
southbridge 1.5v
and all "cpu settings" were disabled (c1e, vanderpool technology, etc.)
I am using bios version 1236 Beta (second most recent on the Asus website.)

The fsb termination voltage at 1.2v is by far the most important setting. The rest of my settings I messed around with until all stability tests passed (prime, OCCT, intelburntest.) If you have any other specific settings you were wondering about, let me know and I'll check out my bios settings and get back to you. These are the ones I remember off the top of my head (and I believe the most important ones.) As long as you have an E0 stepping and adequate ram (that gets to 450+) I would think you would be able to get higher on your cpu with decent voltage and temps. Good luck!

What Biod do you have? I dont have most of these settings.

Crap. Went to update my Bios and It flashed a corrupted file. No problem it has crash recovery and upon me aborting the bios update and restarting the pc asks for a bios file and starts to search USB, Floppy and CD drives for a bios file. I pop in the Asus DVD and it finds the file and restarts. Nothing. fans spin but nothing on screen. Tried moving the jumper and battary and unpluging the power cord and noting. Any tips?
