Had my system overclocked for the past few years and everything was great. I just put in a new video card (512 Sapphire HD 4870) and new memory (CORSAIR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800). Started computer and overclocking failed. I had to revert back to original bios settings. Now I am screwed. CPU-Z had my core speed at 1600mhz when it use to be 3200mhz. Can anyone help me with a new overclock?

Here are my specs:
ASUS P5B Deluxe/WIFI-AP edition.
Intel Core 2 Duo E6600 2.40GHz OEM Processor. Ultra Xwind CPU cooler.
CORSAIR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800
Western Digital / Caviar SE 16 / 250GB / 7200 / 16MB / SATA-300 / OEM / Hard Drive .
Sony DRU810A / 16x8x16x DVD+RW / 16x6x16x DVD-RW / 8x DVD±R DL / Interchangable Bezels White or Black / Internal DVD Writer - Retail.
1.44MB Floppy Disk Drive (Black).
500w ANtec Smartpower 2.0.
SAPPHIRE 100259L Radeon HD 4870 512MB 256-bit GDDR5 PCI Express 2.0 x16
Creative Audigy Sound Card.
Samsung SyncMaster 940mw HD/WS LCD Monitor 22".

Also, is their a way through the BIOS to increase my CPU fan and I am using a very old BIOS (711) should I update it?

i would use beta bios 1238 cuz thats the problems ppl where having mem

and if you havent messed with the bios on the fan its going as fast as it rated to

also how do you flah your bios ?

I overclocked my system and ran Orthos. My CPU temps were very high (65c) and I have never seen my temp that high. I only ran it for 10 minutes and canceled the test. I want to get my CPU temp lower and then tweak it from there. I am not looking to overclock this system over 3.2ghz. I took a bunch of pictures of my BIOS and a few other things. Any advice would be great. Thank you.

3 days and no one here can help me?

[DOM.]

flash your bios to the one i posted im using it and it works just flash it though the bios on in that flash 2 i just save and open then put it on a usb stick and go into the bios and flash

cuz im sure its the ram that made it unstable cuz its 2X2 sticks

then take more pics of the bios cuz its going to change some

[serious1]

I'm have been running the 804 bios for about 2 years now just fine but now that I have upgraded my ram from 2x1gb of double sided ballistix to 4x1gb of single sided ballistix, I cant seem to get the board to post with it. I'm going to update the bios but I'm unsure of which one to use. any ideas?

That a beta bios version. I am using WIN XP media edition.

Don't use BETA, use the 1236. Or stick with the 0711, they were good to me.

As for not using the stock of x9 multi? It's absolutely useless. Stick with the 9x.

Now, try:
CPU Freq: 350
DRAM Freq: DDR2 8xx
PC-E Freq: 101
PCI-C Freq: 33.33
EVERYTHING ELSE TO AUTO
Except Mem Vol to 2.15v

RAM Timings:
4-4-4-12-6-35-10-10-10-10 ("IF" no boot? Try 5-5-5-9-xxxxxxxxx)

Don't forget to change the multi to x9.

I went into the BIOS and put in those settings, but it would not let me F10 to save it. I have never seen that before.

[Nasgul]

I don't use F10, I just go to the very last tab and hit: Save & Exit.

Tried it with both the 4-4-4- and 5-5-5- settings and it would not boot up. I had to unplug the PSU in-order to get back into the BIOS to put back my old settings.

I do not have a multimeter but was interested in knowing if someone could give a rough estimate in regards to vdroop in memory voltage.

If i select 2.15v in the bios is the memory actually receiving 2.15v?

Or is it more like 2.05v to 2.0v?

It's going to depend on the particular board. Mine seemed to undervolt by about 0.02~0.03V when I measured with my old cheap DMM, but I may have to retest with my newer one.

mine was under volted the volts would fluxuate alot when i ran prime etc it seemed to me thats what messed up like 2-3 ram sticks cuz after i volt modded mine the volts dont jump around alot and ram hasn't been rmaed in a long time

Don't use BETA, use the 1236

Beta Version 1236

[Nasgul]

Beta Version 1236

ASUS has changed the page to put all the BIOS from 1212 all the way upto 1236 to BETA version..........when I updated from 1216 which they weren't BETA back then nor had the word BETA Version in RED, the 1216 were official BIOS...........then the 1236 were in BETA and 4 weeks later they were official, meaning no more BETA Version (in red)......

So, go figure what ASUS did........And it's not like I just bought my P5B-D, have had it since July 2006 and definitely NO BETA BIOS were Installed.

As to why ASUS went and changed from 1212 to 1236 to BETA? Well, needless to say that my board came with BIOS 204 which didn't support my C2D, yet the P965 was the "OFFICIAL" release chipset for a C2D.

Maybe you should have paid attention back then and know a little more? That would've helped.

And btw, 0701 and 706 were also official, now they changed to BETA Version. LOL.

well since i updated to 1212 they always been beta bios i didnt look every day for a new bios so i might of missed that

and i don't remember what mine came with its been that long lol

but the 1238 is suppose to work better with 2X2GB sticks since they were not out when the 0711 bios came out

ive used most bios and they all worked i updated to go with 45nm cpus but they where ppl that had trouble with 2X2GB so thats why there still coming out with new ones also not just for cpu's

and is its stable with his old sticks and the new ones are not working what can it be hummm

[RIRed48]

Last week I finally got the below G Skill 4 gig(2x2gb @ 1.9v) to run with the second stick in after I flashed to the "1237" bios. CPU running stock at 3.0ghz.

Today I did a quite mild OC...just cranked up the FSB a bit... to "370" from "333".... so running at 3.33ghz w/ the mem going up automatically to DDR2-1110 from DDR2-1000...black screen/no boot...from what I have read, many people get a 3.6ghz OC with only changing FSB/no voltage changes...pulled battery @ cleared/back to default cpu 3.0 and mem at ddr2-1000.

This little OC...what was the problem?

[In-Fluence]

Hi all, new to this forum (although I've picked up hints from here), but am a long time o/c enthusiast

Just though I ought to have a shameless little brag about my DAW setup...

I've been running my P5B for about 3 years now, and it has served me very well. I began with an E6300 which I spent most of my time running at 3.5GHz but have got up to 555x7 (very nearly stable) on a measily 1.425v! Unfortunately this seems to be the FSB wall for the mb (I'm assuming because I hace a rev C1 P965 chip). The board itself would happily run at 533x7 with just 1.45v to the NB. Following that I got myself an E6600 which I didn't have nearly as much success with, and when I got my Asus C90s I tried my new E6700 in it too which got to around the same 3.45Ghz speeds. I also borrowed an E8500 from work which clocked just as well as the E6300 and got me 4.26GHz (533x8) and it was nice to know this old workhorse still had some beans in it yet!
Anyway - I recently came by a good bit of cash from working hard, and treated myself to a Q6600 G0 and a bunch of watercooling parts. After reading some reports, I discovered this board wasn't ideal for getting big clocks on quads so I half expected not to get beyond 3.2-3.4GHz and honestly thought I was not gonna get the nice and round 400*9 I was looking for, I kept trying many combos to try & get this working but had no joy. Then after jumping to 401x9 the thing started to get stable again! I do however need 1.65v on the nb (1.81v reading using a DMM) which is a bit of a shame, but the quad itself is cruising nicely on 1.4v at this speed, so I've continued to push a bit further....
It seems around 3.75GHz is the absolute limit before the NB craps out with power offs & weird behaviour, and although 4GHz does POST, it doesn't get beyond that :/

Anyhoo - Now I've got this far - I'm wondering if any of you guys might have had any more luck than me with quads on this board and wether you've been able to push it any further than me. I've noticed some of you are running the lovely reapers on here too which I've been able to get running stable at 1200 5-5-5-18 on 2.15v but this is a no-go with the Quad (once again down to the NB strain I think). Any suggestions?

Good to be here, hopefully will pop by every now & then with some more success stories

[mastrdrver]

I think your out of luck with the 965 (P5B in my case) and Core 2 Quads. I have a 9400 and getting 3.2 ghz takes 1.4vtt, 1.45nb, and 1.3 Vcore. Though, my Corsair (I have 4x1gb sticks, but currently only run 2) are taking a crap and not getting to their stock 800mhz rating lately. I'm not sure what is wrong, maybe the memory itself, but didn't have this problem when I was running my E6420 at 3.2 (400x8). I've never given them a lot of volts either. Most I ever did was 2.2, but that was short lived and only posted a couple of times. They stared off at 1000mhz at 2.0 no problem. Now their at 833, not sure on the voltage since I leave it on auto, but the timings have drop from 5-5-5-15 to 5-6-6-15 according to CPU-z when I leave the bios on auto config the timings. I'm starting to wonder if the board, as suggested earlier, might be causing damage.

[In-Fluence]

I've had inconsistent results in the past too, and it sounds to me like you need more NB volts.. Although the 2nd PCI-E channel goes down to 1x when over 1.45v, bumping the PCI-E frequency to 110 resolves this. Trouble is the NB seems to run a bit hotter with quads, and this is after I removed the heatsink, lapped the NB & Mosfet bases down to 1200 grit and bolted them onto the board rather than use those plastic pins which gave a big improvement. Other boards with the same chipset have the option of going 2v+ on it, so I'm pretty sure it can take it.

p.s, here's a screenie runnning comfortably at 3.6 for an eigheen hour prime blend test (:

Does anyone know if this ancient board works with E8500 or E8600 processors?

yes it does i used a E8500 & X3350 on it
