My experiences with OCing on water

[[XC] Synthetickiller]

I just wanted to thank you guys for helping me set up my current liquid cooling system. This has been a blast and still is. I can't really see myself cooling on air anymore.

I'm able to run prime95 on my set up without having the fans blaring loud. 100% load does not require me to change my fan speeds at all. Its beautiful. I'm going to let it run for a while and see if it'll stay stable for say 8 hours, then see what else I can do.

This is what I am currently benchmarking:

Set up:
Asus p5k Mobo
Q6600 G0 @ 3.78ghz
Crucial Ballistix ddr2 800 (6400) @ 840 4x1gig
Antec p180b case
4 Sanyo Denki San Ace 1011's (3 on the rad, 1 in the case + the two stock antec tri cool fans set on low)
x1900xtx (waiting for the 9800gtx)
150 gig raptor w/ vista ultimate
750 gig WD for media storage
120 gig x2 old seagates w/ xp and kubuntu

Cooling set up:
MCR320 radiator w/ 3 san ace fans
MasterLeeker 7/16" tubing
MCRES-Micro
MCP655 pump
D-Tek Fuzion heatblock

I have pictures of my setup, but they aren't the cleanest looking shots. If anyone wants to see, just ask.


I do have one question though. For my ram @ 840mhz, how tight on the timings do u think I can go? Is 3-3-3-9 possible? I went from 5-5-5-15 @ 3.825ghz to 4-4-4-10 @ 3.78ghz and I've noticed a lot of improved loading time w/ the tighter timings.

Did you add 15c to spedfan by chance to get accurate temps? or is that without adding 15c?

That's w/o adding 15, its still acceptable. I'm still figuring out how to do that, lol.

One thing, does my CPU voltage look a tad high? A lot of people are reporting in the 1.40-1.50 range for my sort of OC. I have to keep mine around. 1.57 in the bios, otherwise, I get the blue screen o' death.

Very nice results!

why do you add 15c ?

[Bail_w]

That seems reasonable temperature, but whats your ambient temp?

[Start]

why do you add 15c ?

Because SpeedTemp is off in reading the temperature of most G0-based chips by around 15C.

Its sad that my B3 is running at 1.37v @ 3Ghz and your Q6600 with more volts and speed runs at the same temp as mine. I'll be glad when Yorkfield comes out so I can get some cool (no pun intended) chips.

IDK my room ambient temp as a delta factor, but ...

My cores typically run 19 - 21 , so add 15 to that and I'm looking at 34 to 36*C. At least its under normal human body temp. :D

I am not entirely sure my d-tek fuzion is seated properly. I've tightened it down a lot and do not want to crack the chip. I think my bios CPU voltage is seat around 1.58 or so, so thats understandable idle temp, considering speedran reports 1.54v right now.

SP33DFR34K, thats why I waited for G0. At least you have a $1,000 chip sitting in your computer for less than that.

Nate P., thanks! I am frustrated honestly. I am not sure if my NB needs more cooling than stock, but I can't get anything over 3.825 stable. I've gotten up to 4ghz but its as stable as an egg balancing an elephant. I can run SuperPi 1M though, lol. I think @ 4.0ghz, I get about 1 second faster than my current settings (almost at 13 seconds flat). I wanted to get 4.0 on water. I've seen a lot of guys do that, but I guess I wont' be one of them. It might be that my ram wasn't from a good batch or something. I can't even get 475 mhz stable no matter how low the multiplier goes. Its still good enough to hold me for quite a while. Now all I need is a "good" video card that is DX10 compliant. I do have a 256 mb DDR2 DX10 card, but its an ATI 2400pro that's sitting my old computer. Great for video, horrible for games.
