New H20 setup

Pitspawn · 4 Jan 2007 at 10:16

Ordered a swiftech apex kit the other day with a Lian-Li G70, and am intending on putting the rig in my sig into the new setup this weekend. I will be buying some distilled water too. Few questions,

What sort of overclock do you think i'll be able to get from it? Just to note my ram is 2x512 of DDR3200 (which does 3500 speeds) and 2x512 DDR3500 I plan on buying a hardware upgrade in a few months, but wanted to get the bits that dont go out of date (cooling+case) so i could stagger the cost. Plus this gives me the benefit of squeezing more performance out of my system until I get the other upgrades.

Also wondering if there are any good random tips in advance from any of you vets?

hi

although each cpu is individual an idea about the stepping code could help determine it's general overclocking potential.

If it's a good one then maybe 2.7-3.0ghz but who knows until you try.

Have a look at the overclocking guides around to give you a good start but one tip I can give you is don't worry about using dividers; with the 939's it makes only tiny difference if any.

Thanks for the reply,

On air I've done 2460 rock stable. I can get into the late 2500s before temps become a problem, but i have to drop my memory divider which sucks. I'm hoping I can get away with a hefty fsb overclock so the lower memory divider won't matter. My current case is really small and airflow is a problem, temps should be a lot lower with water and a bigger case.

4 Sticks of RAM will never OC well and im sure you will have to run at 2T.
Dividers on A64 chips dont affect performance at all.
CPU speed is the biggest factor in the speed of an A64, and make sure your memory is running at 1T command rate, 2T has a big hit on performance.
use a 333 divider if you have to and if your mem can do 225 then drop the multi to 10 and up the HTT.
I run 1.55 Volts through my 3700 Sandy and it idles at 32-36C on a swiftech WC system.

Wow thanks for that, just out of curiosity whats your XP3700 running at? =)

2.7 but its a crappy clocker, one of the earlier models.
My 2x1gig Geil value RAm will run at a max of 235 HTT on 2.95 volts (2.5/3/3/7. 1T) so without a divider and at a multi of 11 i can only get 2.53ghz.
If i drop the divider to 333 (166) i can run the HTT at 245 with a multi of 11 i can run at 2.7 ghz (max with this CPU). With this divider my mem is only doing about 180mhz so although mem speed isnt massivly important to an A64 im wasting 55mhz of mem speed.
So if i drop the multi to 10 i can run the HTT at 270 (still giving me 2.7) but the Mem runs at nearly 230.
My mobo can handle nearly 300HTT and my Mem 235 but the limiting factor for me is the CPU hitting a wall at 2.7. Ive even flashed my A8N-SLI Deluxe with a A8N-SLI Premium Bios but the extra volts dont make a difference.
