New quadcore build (pics shown)

juno_first · 8 Jul 2007 at 17:25

Intel Core 2 Quad Pro Q6600 "LGA775 Kentsfield" 2.40GHz (1066FSB) - Retail
OcUK 2GB (2x1GB) DDR2 PC2-8500C5 1066MHz Dual Channel Kit
Gigabyte GA_P35_DQ6 (Socket 775) PCI-Express DDR2 Motherboard
Tuniq Tower 120 CPU Cooler
+
8800GTX @ 648/2000
quad RAID0

The above graphics card in my old system (AMD 4400 @ 2.7ghz) scored 9900 in 3dmk06 & Shadowrun with 15 bots dropped to 30fps.
now
quad core @ 3ghz / 430 bus / 1720 fsb, RAM @ 1075mhz
3dmk06=13033, Shadowrun with 15 bots drops to 90fps.

Had a bit of a problem screwing the heatsink to the board because of the huge slab of copper under the board.
This meant I had to jerry-rig things a bit.
Also as there's now a lot of metal under the board it don't fit on the board tray very well, I call this pic 'the bent mobo':

Now for some fun:
Managed run it at 3.5ghz, although found it to be quicker at 3ghz/higher bus.
Will reach Vista at 3.6ghz but as soon as run prime it dies as the temps quickly rise to 85c.
Will post at 3.7ghz.
I recon with water cooling this beast will do 3.8ghz :eek:

Found the CPU ceiling at 430mhz.
RAM won't do much more than 1075mhz, although have not played with their voltages much.

CPU-Z & mbm showing 4 cores + global cpu temp + system temp in yellow, although recently the 'global cpu temp' has become stuck at 39c no matter the load :confused:

, I found the mbm/core2 plugin for showing all core temps to be about 15c over than the actual temp, so load temp is 72c:

It seams to be running stable at 3ghz & suspect it will do more.
Lost Planet still gives the same fps as my old AMD..(thats an emulator for you) ...LOL.

Nice work mate!

Could you go into a bit more detail about how its quicker at 3.0 than at 3.5? I understand its something to do with the FSB straps or something?

//strokes easy to understand HTT bus

sure...

9x380fsb = 3420 / 950 RAM
7x430fsb = 3010 / 1075 RAM

I think because the fsb/RAM is higher it more than compensates 410mhz core clock.
Its early days yet, I'm still testing.
Right now I'm trying 8x435 = 3480 / 1088 RAM ...just hope the CPU can withstand 435fsb as it dies at 440fsb.

Defcon5 · 8 Jul 2007 at 18:03

So a 125mhz increase in mem speed gives a bigger boost than a 410mhz increase in CPU speed? Must be rather bandwith limited!

What are the FSB 'straps' that people mention then?

(sorry for the questions, im slowly cooking my 3800+ and it may need replacing)

juno_first · 8 Jul 2007 at 18:07

dunno what fsb sraps are, because of the ram divider you cant hit your disired ram speed all the time

72c @ 3ghz. :eek:

Christ these things run hot. Im even considering a basic watercoling system, possibly the corsair nautilus if this tuniq tower doesn't reduce temps from the alomst 80c im getting.

I've just stuck these silent fan things on my tuniq & they are helping.. can now run at 8x420=3360/1050ram, 1.5v
Will tidy up with cable ties soon

Monkey Puzzle · 8 Jul 2007 at 19:07

Looks nice - didn't realise the Tuniq had so much copper on the bottom of it.

Big.Wayne · 8 Jul 2007 at 19:10

I think that extra copper is the motherboards PWM heatsink . . .

i think you are supposed to remove the copper plate under the mobo when fitting an aftermarket cooler

What temps under load?

juno_first · 8 Jul 2007 at 23:24

phew, I only re-enabled the write cache on the hard-drives & 1 left the raid array... oops. anyway back up & running now

Under load with 4 primes its now hitting 74c & with graphics load I guess 80c tops which is ok.

Netvyper · 8 Jul 2007 at 23:38

very impressive

Thats at 1.5v though? can you not get the vcore any lower?

BAMBI · 9 Jul 2007 at 11:11

These quads run hotter then the P4s and i tought that was hot! We need 45nm soon.

juno_first · 10 Jul 2007 at 17:04

New clocking/volts/temps update & still think theres more left in the old .65nm beast with a few more fans LOL.

Interesting how the CPU volts drop under load.

I think the 4x mbm temps must be on-chip & the other temp from the IHS.
These temps are not with 3D though, so maybe another 5-10c running a munchy game for hours.

3dmk06 now 13400 with g80gtx @ 648/2052.

Aren't they compatible with intel tat? wondering how hot they run
only trust tat tbh.

Tried TAT & it only monitors/performs workload on cores 1,2 & is the same as the per-chip temp of mbm.

What sort of cooling would i need for 3Ghz on a Q6600, it will be GO btw.

Dunno about the 'go' chip but I'd get a good cooler around £30 & run the fan on mb voltage control so it runs quiet when idling & fast when working.
