Asus P5Q SE motherboard, memory compatibility questions

post #1 of 5
Thread Starter 
I have a modded Intel Xeon E5450 on Asrock G31M-S that can only work with FSB lowered 8-9, and it's hard to find compatible 4GB DDR2 ram sticks in my country so I ordered an Asus P5Q SE. It has 4 DIMM slots so I thought it would work my Mushkin 996558 ( http://www.amazon.com/Mushkin-996558-UDIMM-PC2-6400-5-5-5-18/dp/B000XH2S9Q ) and I could add 2 more 2GB RAM sticks for a total of 8GB... I couldn't find the same Mushkin 996558 on sale...

Then I saw its manual says this motherboard doesn't support memory modules made up of 128 Mb chips:

The Mushkin ram sticks I have this product description, I underlined the part that boggles me:

Mushkin 996558 DDR2 UDIMM (2x2GB) 4GB PC2-6400 5-5-5-18 NONE 1.8V Compatible Frequency This product is engineered to operate at the optimum frequency for compatibility with your system. Compatible Timings This product is programmed to use timings that offer maximum compatibility with your system and original memory. Dual Channel Kit Engineered for dual-channel architecture. Lifetime Warranty Quality guaranteed - we offer a lifetime warranty on this product and genuine, unmatched service and support. Type: DDR2 Voltage: 1.8V Speed Spec: PC2-6400 Frequency: 800MHz Capacity Kit Type: Dual Kit Module Size: 2GB Module Build: 256Mx64 Chipset Density: 128Mx8 Timings tCL: 5 tRCD: 5 tRP: 5 tRAS: 18 Cooling Technology Heatsink: None

1) Now, I wonder, will these ram sticks work on Asus P5Q SE or not ?

2) If they will, what to look for a memory upgrade to fill the other 2 slots ?

I think a total of 8GB will be good. Do I have to find 2GB memory modules working CL5 800 MHz, or do I need sth more specific to most likely work without a problem like a 5-5-5-18 timing, or would sth less specific most likely work too ?

3) If they won't, do you have other suggestions ?

Hi there,

I was checking the specifications of the motheboard you mention "ASUS P5Q SE" and there are a few things that got me thinking.

Im not sure why you said that the asus P5Q SE support your xeon CPU, I read, and checked the CPU support list of that mobo and there are no Xeon CPU on that list. As far as I know they have all that list updated because they are the MFG, but I could be wrong.

here is the list supported CPUs

As for the memory ram, as a general rule you should go with RAM that's tested and approved by the MFG, you can check this by looking for the memory support table on the website, here is the link P5Q SE Memory QVL

by doing this you will guarantee that all your components will work together pretty good thumb.gif

I hope that helps,

Cheers rolleyes.gif

this is OCN bro. http://www.overclock.net/t/1431723/mod-lga775-support-for-lga771-xeon-cpus/0_20

People are running older Xeon chips in their 775 build to beef them up a bit to get more life out of it.

As far as the memory compatibility, while it is a good idea to get a supported memory module, the motherboard will likely run as long as the sticks are the same type, DDR2 6400, etc. I am pretty sure half of my build are running memory that isn't on the motherboards "supported" list.

I know tongue.gif, Im using RAM that is not on the QVL, but the thing is that I dont do bios mods to support CPU and Memory, so I just gave my suggestion rolleyes.gif not that he have to do it tongue.gif, That's also why that I could be wrong redface.gif

xeon support to my understanding is a sticker that flips a couple pins on the 771 cpu to work in 775 board. no bios mod needed.
