Yes. But this is relative a little work. Besides, writing BIOSes is the main job of the BIOS engineers, no? :)Quote:

I do remember there being a bunch of issues with 65nm C2D and I think there was a microcode update for those.
Yes but there are no explanation how exactly it is implemented. I suppose the most BIOS fixes are implemented through microcode update. And, possible, it was already done.Quote:
If you look at the list of errata there are a lot of "bios workaround" mentions. For example the most recent addition - AW51 from 02/01/2008.
I guess we'll just have to wait and see if there are updates that fix some things or not. Aside from errata I think there may be need for lower voltage settings in some bioses to meet the specs..
Here is my Aquamark3 result at 4850mhz with single 8800 Ultra.:D
Just built my new machine this weekend: E8400, Tuniq Tower 120, Gigabyte P35-DS3L, 4GB DDR2-800 SuperTalent, EVGA 8800GT, 150GB RaptorX - All these bought new. I'm using my old Antec Sonata (the original) case, and OCZ 520W PSU (still under warranty).
The new machine was built so I can play DX10 games, as well as be able to run it 24x7 as a web/app server, so it has to be quiet. My previous rig had 6 fans and was very noisy (X-Alien case, opteron 165 @2.7GHz, Asus A8N-SLI, 2GB DDR-400, XFX 7800GTX OC, 150GB Raptor, same OCZ-520W PSU.
Anyway, without wasting too much time, I overclocked it to 400MHz FSB, CPU @9x400=3600 MHz, 1.325 V. Temps are 32C idle, 59 load - with the Tuniq Tower 120 CPU fan at the lowest setting (1000 RPM). If I disconnect the case fan (a single 120mm rear exhaust), the temps increase by 8-10 C.
I'm currently shopping for quieter case fans, and possibly a VGA cooler.
I haven't overclocked the video card yet, so 3DMark06 score is around 11.5K.
I'm very impressed with the Tuniq cooler. I even left it overnight with CPU and case fans both disconnected, and it still managed to keep the CPU below 60C (idle, closed case).

rofl -ive had to have an arguement with scan.co.uk to get my cpu rma'd after my psu blew up as apparently (quote the chap) "ive never had to rma a cpu and these have been out for 2 weeks so i doubt they will die"
Bit confused with temps.

This is at 4.23Ghz - 1.416v REAL * 1.372v LOAD
What im confused about is, WHY am I getting a bunch of different readings on different apps, example, core temp reads the 2 cores @ 65/65C LOAD, speedfan is reading CORE @ 55C and CPU @ 45C
What the fook is WHAT ??
I am not worried about my temps, I have nothing crazy on vcore and a good cooler - the TU120 EX, I just wanna know what the hell is what!
:(
have you tried everest or uguru?
I have an early version of everest but it does not recognise my CPU and the latest version just says I need a key - but the early version says the same CPU temp as speedfan.

EDIT: OH WAIT< it seems speedfan is STUCK on 54 CORE temp.
I find this part very interesting: Our temps problems?:Quote:

Problem: Software can enable DTS thermal interrupts by programming the thermal

programming DTS value, the previous DTS threshold may be crossed. This
will generate an unexpected thermal interrupt.
Implication: Software may observe an unexpected thermal interrupt occur after
reprogramming the thermal threshold.
Workaround: In the ACPI/OS implement a workaround by temporarily disabling the DTS
threshold interrupt before updating the DTS threshold value.
Status: For the steppings affected, see the Summary Tables of Changes.
& this the part i found interesting - Plan: No Fix :rofl:

e8400@4Ghz vcore bios@1.4325 =1.408 real= 1.384v load
Anyone have the release date for the E8600 with 10X multi?
Is it true that the max FSBv u may apply for these chips is 1.15v? cause I have my FSBv @ 1.40 now, so it worries me abit oO
That is the official Intel spec but nobody around here ever listens to stuff like that. :DQuote:

Gaah! Can't Understand why both the U.S. versions of this cooler (Xigmatek and Kingwin) come with the push-pin mounts! They don't provide enough pressure!Quote:

My box says 1.225v max, or is that reffering to the CPU VTT?Quote:

Not to mention that 8800GT is idling at 75C (not overclocked), which seems way too high. Damn Nvidia and their sub-par stock cooling.Quote:

This is exactly what I was hoping would happen with a cpu exchange, lower volts and 4ghz stable while closed up in my desk on air cooling.
I know I'm not in the same ballpark as some of the other extreme numbers, but I have slow RAM that doesn't like much more then 480FSB and really, 4ghz is good enough for me. I included my settings from uGuru if anyone was curious.

CORE is your GFX card, the other temp is cpu diode. Thats the way new speedfan works, misleading I know.Quote:
