144 CAB2E / 7800GT's Overclocked a Treat

Predator · 18 Jan 2006 at 07:43

Built my new PC at the weekend which contains the following:

AMD Opteron UP 144 San Diego 1.8GHz 1MB Cache (Socket 939)
DFI LanParty NF4 SLI-DR EXPERT (Socket 939) PCI-Express
Western Digital Raptor 74GB WD740GD 10,000RPM SATA 8MB Cache
G.Skill 2GB DDR HZ PC4000 (2x1GB) CAS3 Dual Channel Kit
NEC ND4551 16x16 DVD±RW Dual Layer ReWriter (Black)
Thermaltake Armour Case (Black)
Thermaltake PurePower TWV 500W ATX2.0 Modular PSU
2 x XFX GeForce 7800GT Extreme LED Edition 256MB GDDR3 VIVO
Thermaltake Watercooling Kit

I currently have my oppy running at:

2792.3Mhz (9 x 300Mhz) - (4 x HTT) - (166Mhz divider)
CPU: 1.525V (idles at 30deg - 38 on full load)
LDT: 1.37V
DRAM: 2.83V
NB: 1.64 (idles at 50deg - seems a little warm)

memory has been left on auto

CAS#: 3.0
RAS to CAS#: 3
RAS precharge: 3
Cycle Time: 6
Bank Cycle: 7

Geforce 7800GT's are both running at 490Mhz (up from 450Mhz)

I get 12312 in 3DMark05 which is kinda nice.

If any one has any comments or suggestions regarding this build so far, I'm open to suggestions. TIA!

Update your signature?

Predator · 20 Jan 2006 at 13:22

After all that, all you have to say is update your sig...

thx for the feedback

Baker · 20 Jan 2006 at 13:24

You did it though didn't you.

As for feedback... I'd shag it.

Predator · 20 Jan 2006 at 13:25

you can have my sloppy seconds then :eek:

Jameslee · 20 Jan 2006 at 13:34

Would I be able to get anything near this? I have the same RAM as yourself, but the stepping is cacje and the board is the DFI Infinity.

hoping to at least reach 2.5/6

But thats a nice clock you got there, as well as the score

Predator · 20 Jan 2006 at 13:39

Like youself, up to around a week ago I was a total noob to this. One of the main things I've learnt is that no matter what gear you buy, every set up is different and the main thing you need is "luck" and "patience"!

With that RAM, the cpu will tick over at 2.25 (9 x 250FSB), but the work starts when you tinker with HTT settings and voltages.

I don't think anyone here can say for sure what speeds you'll get, but I reckon you should get up to 2.5 / 2.6

Just don't rush it. End of the day we're all as bad as each other here. Get 2.5 and you want 2.6. Get 2.6 and so on!! Just make sure its cooled, its stable and put together 110% right!!

My plan was to spend the least and build the best for bucks. I was lucky

2792.3Mhz (9 x 300Mhz) - (4 x HTT) - (166Mhz divider)

HTT=4x300mhz=1200, shouldn't this be under 1000? Have you tried lowering it to 3 and pushing the fsb further?

brocksta · 20 Jan 2006 at 16:09

is it prime stable? also thats a lot volts going through the poor thing. Although i suppose its down to personal preference really.

Predator · 20 Jan 2006 at 18:45

Yes I've tried HTT x 3 and running at 310 but its not a happy bunny.

Its VERY stable running Prime etc at the current speed

malccy · 20 Jan 2006 at 18:54

Good clock mate. It does'nt have to be under 1000 although a preference; so 1200 is fine.

Predator · 20 Jan 2006 at 18:55

Ahh kewl.

Just wanna get it up to 2.8 but it just doesn't wanna have it!!

Here it is in all its glory

Itsjody · 20 Jan 2006 at 20:21

I got mine running at 2.8, 9 x 3.12, HTT @ x 3, memory at 166 divider, prime stable for 24 hrs

Predator · 20 Jan 2006 at 20:39

Can you let me know what voltages please?

Itsjody · 20 Jan 2006 at 21:35

MBM5 reports the following:

vcore&vid - 1.49
LDT - 1.63
DRAM - 2.74
Chipset - 1.49.

It runs at about38/39 idle and about 48 full load.

Predator · 21 Jan 2006 at 08:45

LDT seems a little high, but I'll give it a go later on today.

Thanks

I updated the bios on my motherbaord, and it seems to have taken away the option to change the LDT volts.
