AI7 + typical P4 3.4C

[eva2000]

Just swapped my 3.4C out of my vcore challenged Epox 4PCA3+ into my AI7 for some fun (need a break from testing BH-5 ram all the time with my 2.8C). Seems to be a typical P4 3.4C not exceptional in anyway vcore voltage wise still needs alot of vcore to perform but i'm in 30-34C room temps using less than ideal heatsink for now.

Running Windows 2000 Pro SP4 with latest windows updates and DX8.1

note: cpuz has problems reporting right ratios set in bios on AI7 when GAT is in play to enabled PAT fully, i.e. 1:1 is reported as 5:4 and vice versa

I wonder how much more FSB i can get watercooled (30-34C room temps) or mach2 cooled ?

[ibby]

not bad mate.

is that 1.8v on air ?

a decent water rigg will be alot of $$$

nice results

[eva2000]

yeah on air with MCX478-V at 1.8v in bios is only giving 1.68-1.74v fluctuating in windows though under load

changed out 2x 256MB KHX3200K2/512 BH-5 for 2x 512MB KHX3200/512 BH-5 sticks and played with AI7 sprindale boards' GAT settings some more. Just more stock benchmarks to get an idea of how a 3.4C performs for reference.

Hexus Pifast = 73.72s - strange pifast was slower

I think I'll need to install WinXP PRO instead of Win2k PRO SP4 and see how things differ as well

I took delivery of my Corsair Hydrocool 200 water cooling external unit yesterday and after 8-10hrs leak testing seems fine so decided to install HC200 on my AI7/3.4C

Took me a while to figure out where to place HC200 unit so decided to use a chair besides the mobile utility trolley pc setup (i'll post pics later)

I used Ceramique thermal paste since it's non-conductive. I did a test mount, and to my surprise when i tried to remove the cold block to see the cpu imprint on the cold block to see how well it contacted, i found out that the cold block was stuck to the cpu! Eventually pulled the cpu out of the cpu socket stuck to the cold block

I find this happens more when using aluminium heatsinks such as my Igloo 4300 100% aluminium fin HSF as well. Luckily there was no damaged cpu pins .. phew!

Reapplied some ceramique paste and reinstalled the cold block. Booted pc and I love the temps I'm seeing

---------------------------------------
Results with room temp at 28.5C - 28.8C

HC200 cooled

At boot in bios
cpu idle = 39-41C
system idle = 29C
pwm idle = 34-35C

At boot HC200 display = 28.5C - 29C

In Windows
cpu idle = 39-41C
system idle = 29-30C
pwm idle = 34-35C

2x Prime95 v23.8
cpu load = 45C
system load = 31C
pwm load = 47C

HC200 Display under prime load = 31C - 31.5C
------------------
Conclusion:
1. On average at stock P4 3.4C speed and vcore, HC200 water cooling reduced my cpu idle and load temps by 4-6C compared to my previous air cooled setup of Swiftech MCX478-V with 80x38mm Delta 80cfm fan on high speed.

2. HC200 displayed idle and load temps are ~10C and 14C, respectively lower than actual reported bios/board temps at stock 3.4C speeds and vcore.

Need to do more testing though and I'll post some pics later on
