LanpartyB & BH-5 @ 245mhz 3.3v, Want to go higher!

[Kinsy]

As topic, im topped out on the FSB front @ 245mhz fsb 3.3v CAS11-2-2-2-9-12, CPC Enabled. Day to day im running 10x243mhz now as my CPU primes @ 2.43mhz ok and doesnt cause planetside to lock my machine every hour. This is with 3x256mb sticks in. I really need 3 sticks in for Planetside especially as the extra ram stops the jerking.

I have the following sticks of memory, all 256mb.
3x Kingston HyperX PC3200 KHX3200/256 A02 2.6v - Definatly BH-5 So far had all 3 in at 245mhz 3.3v.
2x Corsair XM3500 PC3500 bought January 2003 - not sure if theyre 1.1 sticks, but i hit 254mhz fsb @ tight timings with them, so safe to say theyre BH-5.
OCZ PC3500 with what looks like an Adata-based stick underneath (i can see Adata written on the PCB). This works about as well as the Kingston.

Ive had it up to 255mhz fsb passing memtest with the corsair alone, but im really aiming for 9.5x255mhz fsb with 3 sticks filled.

CPU is at 1.9v, chipset 1.8v. This has the stock passive cooler fitted, which may be a concern. CPU is LRWW'd up with a 2x120mm rad, Maze4 on the GPU, Eheim 1250 & Bayres, so coolings ok. BIOS is flashed to 1-21 beta.

Right now im considering some better cooling for the north bridge and some cooling for the vreg chips, would it be worth doing so i can use less voltage on the memory (but more stable) and get a higher fsb?

yah i think youre gonna need more vdd and cooling for the chipset and the mosfets. that should bump up your stability in prime

your BH5 looks to be performing on par so i would look to other things

Get some good air over that stock NB heatsink, after making sure it has the proper application of thermal compound.

Get some better cooling on the southbridge, heatsink the mosfets.

I personally doubt that you need more Vdd at this point. The two Infinity's I've had don't need much on the chipset, mine are more stable 250X10 at 1.6 or 1.7 Vdd than at 1.9, though only slightly more so.

Passive sinks on the mosfets, pll, voltage reg. chip & south bridge. I'd get a Swiftech or Microcool active air NB cooler along with some AS 5 on that NB. For the very best results, use epoxy thermal glue to attach the passive sinks. You'll lose them if/when you sell the board, but will get the most results for you this way.

If you don't have a side panel fan/blower fitted, then I'd install a 120mm (quiet) to cool the whole board overall.

If there is more to be had without a mod to increase the voltage, then this extra cooling should allow you to get it.

One step ahead of you.

Theres a 120mm 125cfm YStech blowing over the whole area in question (nb, mosfets, cpu socket, memory).

I dont want to spend a load of money, and im not watercooling the north bridge (too much of a flow killer). I was going to get some of those Microcool Mosfet cooling kits, but theyre out of stock everywhere in the UK.

sjohnson is bang on there about the nb voltage - it doesnt need much, i could probably drop it to 1.7v easy enough.

Anyone know where i can get the whole deal (mosfet sinks, new nb heatsink, as thermal epoxy) in the uk?

Temperatures by mbm are 30deg nb, 38deg cpu (internal diode), 42-45 load.
