@telstar - I too am considering purchasing one of these (GA-EG45M-UD2H) but it must have the ability to undervolt in the BIOS. Does it for sure and how low can it go?

Other than that how are you liking the board and have you tried using Linux?

@JoeTheZombie - Nice build dude. I am considering that motherboard and was wondering if you could tell me if it allow under volting in the BIOS? I have an e5200 that runs stable @ 0.9750 V even though the stock VID is 1.2875 V. Under volting it drops the temps by about 20 C. Please let me know and t...

I need an mATX form factor MB that'll take an Intel 775 CPU (I have a spare e5200) that has the following key features: 1) Ability to set the CPU vcore, not just add to the stock VID (I want to under volt). My E5200 has a VID of 1.2875 V but runs perfectly stable @ 0.9750 V. 2) Southbridge that isn'...

Great info, thanks for the reply.

I just bought a Western Digital Caviar Black WD7501AALS 750GB (SATAII, 7200 RPM, 32 Mb cache). I ran a few disk benchmarks on it and found that is seems pretty darn slow compared to my Seagate drives. Does anyone else have this WD drive and would you mind running HD Tach on it if you run windows or ...

Edited on 08-Jun-2008: Guide is now version 1.7 – added a 2nd example minimizing the vcores on my system.

Got bored yesterday, so I ran checked out the power consumption of my X3360 system for shits and giggles with my kill-a-watt. http://img519.imageshack.us/img519/8808/killawattdi8.jpg Powered Hardware Details: Intel X3360 (C1 stepping) @ 8.5x400=3.40 GHz 266/667 MHz Strap CPU Vcc=1.12500 NB Core=1.37...

I edited the first post switching the highest 400 MHz FSB run from 5:6 to 4:5 (960 MHz vs. 1,000 MHz) and included some info about subtimings to make things more clear.

About 7 months ago I posted data comparing two memory dividers (1:1 and 3:5 @ 333 MHz) on my then Q6600/P965 based system and concluded that for the 67 % increase in memory bandwidth, the marginal gains in actual performance weren't worth the extra voltage/heat. Since then I've upgraded my hardware ...

Version 1.6.1 is up. Totally re-wrote the section on memory which now includes a discussion on both DDR2/DDR3 and formulas you can use to calculate max supported FSB of a given module based on it's DDRX-Y and PCX-Y designations. Also re-ordered the first part of the guide.

Guide is now version 1.6

• Added a detailed section to help you find the minimum stable CPU and MB vcore settings. Check it out (near the bottom of the guide entitled, “Stress Testing and Minimizing Your Vcoresâ€

Well, guys I wrote up this procedure I used to minimize my vcores on my new x3360/P35-based system, and I thought I'd share it with folks. It's a systematic method anyone can use to arrive at a minimized set of vcores for a given multiplier and FSB value. The examples I present in this post are usin...

Well the HS is just half the story. Have a look at the results I got after lapping the IHS on my Q6600 as well Yeah, I remember readng your thread with the biggest gain achieved from lapping the Q6600. still 66 c isn't that high for an OCed Q6600 on load. I'm confident you are happy with the +- 10 ...

Well the HS is just half the story. Have a look at the results I got after lapping the IHS on my Q6600 as well

Version is now 1.5.2 (updates in first post)

@Silviu and JimX - thanks for the data. Will update shortly.

Wow dude, you tested the hell outta that system. Thanks for the data.

Cool, got it!

Thanks for the data, guys, will update the tables shortly with your results.

@thejamppa - is your 4000+ a Clawhammer (130 nm) or San Diego (90 nm). If you're unsure, CPU-Z will tell you on the first tab.

Techarp is hosting a new HD x264 benchmark . Have a look and run it on your system to help populate the data table. Basically, you run the test encode of an HD sample (1280x720) and it will report back frames-per-second values for your machine @ it's clock/overclock level. You can run it at your sto...

Minor update made.

First off, thanks to all who contributed data. 24-Feb-2008 - Finally updated the data tables on the x264 benchmark page . They are now html based (not .gif images) which makes my life updating them much easier and I will keep this tables up-to-date daily as people post results. Have a look at the 'D...

Updated the tables with another 45 nm chip: the QX9650 -- both at stock levels and @ overclocked to 4.2 GHz! With it, and the others (Xeon E5330 (Dual board), Q9550, and Q9350) there is now data on 4 different 45 nm chips. One thing that I found striking about these new chips is that they are only m...

Thanks for the info, dude.

Just updated the guide to version 1.3 which contains new info, fixes, clean-ups, etc. Enjoy!

Common sense tell you that higher memory bandwidth should mean faster results, right? I set out to put this thought to the test looking at just two different memory dividers on my o/c'ed Q6600 system. At a FSB of 333 MHz, the slowest and fastest dividers I could run are: 1:1 a.k.a. PC5300 (667 MHz) ...

Updated the Intel table. It now contains several Yorkfield ES chips including:

Xeon E5330 (Dual board)
Q9550
Q9350

no change @ 42

I just bought a pair of BL2KIT12864AA1065 and they will work in any mode except the fastest two. These work fine: 1:1 (533 MHz), 4:5 (667 MHz), and 2:3 (800 MHz). If I boot them in in 3:5 (889 MHz) or 1:2 (1,066 MHz) windows will not start. If I boot into Memtest86+ V1.70 , they give TONS of errors ...

@dark: I think the multiplier on your chip is maxed out @ 10.5 can you report the multi and fsb? Also, what is the clock speed of the RAM (800 is the specs right?) Can you post the CPUz.html dump?
