Asus P5Q-E (P45) Motherboard Review

regarding going above 450fsb and 1-1 memory, did you get it sorted ok
Hey setter,

I think the ASUS P5Q-E (and perhaps all Intel® P45) really work a lot better if you put the memory on a divider (or should that be called a multiplier).

At a humble FSB of 400MHz (1600MHz System Bus) this board supports 600MHz memory frequency (DDR2-1200) and the system flys! :eek:

If you want to improve your overall system performance and get a really *snappy* feel then pick up some faster DDR2 . . . . some DDR2-1066/DDR2-1200 would work nice with your Q6600/P5Q-E combo! :)

Pretty happy with this on my P5Q, it's both game and prime stable, memory is OCZ 8500 Reaper (2 x 2Gb) . I set the voltages as per this thread (a step or 2 above minimum) and manually set the memory timings, other than that most AI settings are still on Auto. Cooling is via a Freezer 7 Pro, 100% load temps are 42c.

Headache!

Alright lads, finally had some spare time to play with the the P5Q-E/E8400/Crucial 10th and thought I'd see how the memory overclocked!

Seems to work well in this motherboard and got it up to about 600MHz (DDR2-1200) without going crazy with the vDimm! :D

I had quite a problem with Prime Large-In Place FFTs and also IBT constantly failing and took quite a bit of headscratching to work out what was going on! :confused:

After a lot of trial and error I eventually found the elusive memory subtiming that was holding me back . . .

Changed it in Windows using Memset and the problems went away? I don't understand that much about all the different memory sub timings yet but it seems the board was setting it to aggressively? I suppose it may be due to the Crucial sticks having [SPD] info for DDR2-667? . . . anyway thought I'd mention it just in case anyone else has a similar problem! :cool:

I had to dig around in the BIOS trying to find it also so heres a screenie for anyone else who needs to find it! ;)

Hello all! :)

I'm just getting back into this thread and getting my system set-up again. I sold my Original P5Q-Deluxe last Sept and dabbled around with an ASUS P5Q-EM/E5200 combo but sadly it wasn't that easy to overclock so I decided to pick up a used ASUS P5Q-E and try to finally get some great results on the LGA775 platform! I've now got a retail Wolfdale E8400 and a much better idea of how the Intel® P45 Express Chipset works so hopefully over the next week or two I can improve my settings and get a great 24/7 overclock going on!

The screenies above are where I am at, very nice and stable and a great system to use daily. I did hope to have a bigger CPU, FSB and NBCC overclock by now but I got carried away with playing with my DDR2, I never realised it could run so fast, I also didn't realise that the Intel® P45 has such good support for fast memory! :D

As I hope you can see the voltages are all nice and low atm and the system is nice and stable, I can set the PL(tRD) as low as 6 but it's not stable yet . . . but with more vNB I'm sure it would be . . . anyway as has stated again and again its better to get the big stuff sorted then come back and tweak, so thats what I intend to do.

I am thinking of trying for either 450MHz-FSB next or perhaps jump straight to 500MHz with the CPU on an 8x multi and try the memory on a different strap but keeping it at around 600MHz (DDR2-1200) for the moment.

I am interested what you guys think will be the *key* voltage differences between 9x400 (as above) and 8x500?

Nice clock you've got going there....and you never knew that Ballistix clocked like that? :p How much voltage are you giving them?

btw for 512fsb I need 1.2 FSB-T, 1.28-1.3NB....Try PL10 and mem @ 1:1 ratio first though if you are going to go for 500fsb.
 
very nice vcore for the clockspeed:cool:
Ta! . . . I didn't think it was anything special as I'm sure I saw a few golden E8600's running 4GHz @ 1.1v :(

Still looking on the bright side I'm happy I managed to undervolt it and overclock it, with a VID of 1.2500 I'm not expecting great things from this chip . . . 4GHz would be swell! :o

Well I kinda knew by proxy they were meant to be nice rams but I never really understood how the FSB-Straps worked until recently so these sticks have been running at 400MHz 4-4-4-12 1.8vDimm since Jan 07 :rolleyes:

anyway running at [2.06]vDimm in the BIOS, don't know how to use a DMM but by all accounts the boards gives an extra 0.08v . . . . . so 2.14vDimm actual for 600Mhz 5-5-5-15

I'm a wuss anyway and a lot of peeps from this forum have given me the fear so I stuck an 80mm fan on them just in case lol! :p

Thanks! :)

My key voltages for those settings were.

CPU PLL: 1.6v
VTT: 1.34
NB: 1.3
SB: AUTO
PCI-E: AUTO

I havent tried reducing performance level to 10 from 13, but iirc ive seen it reccomended somewhere in this thread, along with gurusan's post above. That was my previous set of ocz reaper 6400 in those screens, i ran it with the timings loosened from 4-4-4-15 to 5-5-5-18. Ive since upgraded to pc8500 reaper @ 5-5-5-15

13 is pretty loose and will affect your memory bandwidth by quite a lot. You should be able to get down to 8 or 9.
 
Thanks cob, will have a crack at lowering it down, got the rig running at stock at the mo. (crikey it's slow):D, had to dismantle the system to give it a bit of a clean and swap out hard drives and reinstall the os.
 
I'm breaking through a massive learning curve at the moment and all the things I've wondered about are finally becoming clear (vTT, GTL, PLL etc). :cool:

I've got a couple of fairly simple questions that hopefully the advanced users will be able to clear up for me! :)

Firstly, why is it that on a ASUS P5Q-E and a Wolfdale E8400 I get two options for CPU GTL? I kinda thought that maybe the first option would be for tweaking a CPU with two cores (0/1) and the second option for tweaking CPU with four cores (2/3) but looking at the numbers in the BIOS it seems not as the first says (0/2) and the second says (1/3).

If it's both options just for a dual-core then do another set of GTL refs appear when you install a Quad? :confused:

Second question, until today I though the NB GTL Ref was linked to the NB Voltage but having done a bit of reading it seems that NB GTL Ref is also connected to the same vTT (FSB Term.) control above for the CPU or?

Is NB GTL Ref relating to the NB Voltage directly above it? . . . or is the NB GTL Ref relating to the base FSB Termination (along with the other two CPU GTL options above).

I'm just new to this whole GTL thing so sorry for what may be really obvious questions lol! :D
