You will also lose all readings of other voltages by any applications.. and the 'extended' memory settings kinda drops you no where. OC is simply bad..

I'd stick on 0702 BIOS (or perhaps in RF BIOS, if good set going on) since I also tested the new 0903 and it seems even while it allows higher OC on memory & seems functioning while OC'ing better it is incredible unstable BIOS when you compare to 0702 (if you do update to 0903 you will want to reinstall your Windows Vista/XP also because you'll face blue screen hell for some reason tested this twice).

So there's my BIOS advice to everyone for now. v1.200 = v1.168.. that drops yes but something like v1.2350 = v1.208 which only drops to v1.188 on LOAD. So counting that while OC'ing is pretty good. Also if you got NB as 'Auto' I'd watch a bit anythin you OC will make ASUS-P5E to top notch all Voltages so Auto while OC = ~1,6v NB..

Memory 2.00v = ~2.108v (and memory goes pretty accurate exact 1.00v over the setupped value)

Thats funny, I havent heard anyone having problems with the P5E Deluxe BIOS. I find the 0205 BIOS to be very stable. My vdroop is not bad at all either. I have it set to 1.4v and it drops to 1.376v in BIOS (havent done the pencil mod yet). I have also used the Rampage Formula 0410 BIOS and never had any problems. I never had to reinstall my OS and I have flashed 7 or 8 times. Perhaps you are doing something wrong there.

Why would you leave NB voltage on "auto" in the first place?

After putting the Rampage Formula BIOS on the P5E Deluxe, I'd suggest that the 0205 Deluxe BIOS is bad for the P5E Deluxe.

Are there any differences with settings besides those associated with the added features included with the Rampage Formula board itself? The Deluxe has all the same features as the Rampage Formula bios.

What specifically is better about the Rampage Formula bios?

I could not get 3.6GHz to anywhere near stable on the P5E Deluxe 0205 BIOS. It would crash almost the moment you put the CPU under load. On the RF 0410 BIOS, I'm using it under 100% load with temps around 65°C, almost no Vdroop, and I'm probably just a few slight tweaks away from getting it 24x7 stable.

So, does P5E original 0702 & 0903 drop is 1.4v to 1.376v or in my case it's 1.200v to 1.188v on load. Can you read your other voltage sensors?

I didn't either see any problem using it, but missing information, exact same quality on voltages & as bad OC with no advance on memory is in my opinion absolute waist of time to update.

Have you changed the Transaction Booster (tRD) at all? That is the biggest change in the bios, and it gives you much more control over your Chipset and ram OC.

I have not yet used the original P5E BIOS, only the Deluxe and the Rampage Formula. As Eric mentioned, what do you have your Transaction Booster set to? It plays a big role in determining overclock stability. I would recommend setting it to 9 or 10 when initially overclocking and then lowering it once stable. Lowest I can get mine to is 7 at 400x9 on 1.4375v, NB at 1.43v, RAM set to 2v (since overvolts by .09v) with timings of 5-5-5-15 and tRFC at 45.

whats the average fsb with this board using e8400?

I dont know about average, But I easily churned out a 515 FSB with only 1.43v to the NB using the P5E and an E6600 (see my post on the first page of this thread).

yeah it's enabled Performance level 6. (you can get this level on EPP profiles sadly on manual to OC best is Enabled 2 = Perf.Lev. 7). btw, I find those latencies of Write recovery and write in general very odd.

My board is as below said G.Skill base Memory speeds in stock speeds I get like 9200MB/s which is incredible good by simply latencies, 1:1 and FSB simply 400Mhz. I honestly think my Q9450 on 3,2Ghz is faster than 3,6Ghz I was also running 8-12 hours ORTHOS there stabile on 3720Mhz on 1.43 NB and alot higher VTT than yours on original post as at least my P5E BIOS drops VTT to actual 1,26v on 1.36v. So it needs to be much higher than NB to get stabile. Also your Memory voltage is incredible odd I don't know how your board functional on voltage but if I stick 2,14v on DDR it's close to 2,24v actual Perhaps 2.16v(on bios) even tho on 1066Mhz clean.

Also CPU voltage set as 'Auto' is interesting example as said before that CPU voltage is dropped from 1,2350v(bios) o actual 1.21v system now if you OC (This means you set ANY manual value to FSB) setting Auto actually maxes vCore automatically to 1.325v very very stable no drops on load. So this maybe could be used to actually find the maximum core performance around 4,256Ghz.

(Although your Q6700 is so incredible core considering the OC's on Q6600 G0 cores I've seen that should go over 4Ghz ""with eas.."")

Quick calc on performance level 0702/0903 BIOSes P5E:

( booster value = Performance Level )

Transaction Booster:
Auto = 10 or 11 depending on Static read I think. I get 10.
Disabled: 
7 = 1, 6 = 2, 5 = 3, 4 = 4, 3 = 5, 2 = 6, 1 = 7, 0 = 8
Enabled:
7 = 2, 6 = 3, 5 = 4, 4 = 5, 3 = 6?, 2 = 7, 1 = 8, 0 = 9

The 0205 so called advanced Performance level is just fine tuning the Performance levels by blocks so that kinda helps, but not by falsely detecting 6 blocks as 0205 does.

( Recommended setting to 9 or 10? hell anything above 7 is bad enough.. I hope manual could reach 6 on 1066Mhz, but only EPP profile usage reaches 6 for some reason otherwise it won't post. )

O and fail to mention..

0205 P5E-Deluxe BIOS Performance level = BIOS != Performance Level... Test it on 6-7 and you will see your performance level is not 6-7..
