Asus A8R-MVP Mobo and RAM question

[koocha]

Hey

In my current rig I've got 2 x 256Mb sticks of PC3700 and 1 x 1Gb stick of high density PC3200. I'm having to run my ram at 166Mhz because it doesn't detect the 1gb stick otherwise.

So my question is...with the asus mobo being double channel and everything, can I fit all my ram in or will I have to buy more?

Cheers

What kind of processor and core are you running? The older Athlon 64 cores cannot run more then 2 DIMMs at PC3200 speeds.

BTW, how do you find the board? I'm considering one myself

Hey

I haven't got one yet, that's why I'm checking if it'll run ok

I'm really liking the look of the board, and SCAN sell it. I would have gone with the ECS crossfire board if SCAN sold that one.

I'll either be running an Opteron 146 or a 64 X2 3800 (dual core) depending on the outcome of my other thread!

I have an Opteron 146 and 2gb of Gskill HX memory so would also like to find out if there are any memory issues on this board.

What I'm trying to get at is if I can run it as 3 seperate memory modules or if dual channel takes over?

I have built a comp for my bro with that board and a 146. The 146 topped out at 2.6Ghz (10 x260 - 183mhz divider, ram @ 234mhz - didn't bother trying 9 x300) due to the SEVERE voltage restrictions that board has. The cpu was only at 44C load on the stock cooler at 1.45v.

This board has a real issue with voltage as it cannot go any higher than 1.45v even with the "overvolt" option enabled. Asus need to release a bios for this board that will allow it to put proper volts through the cpu. It may have issues running older AMD 64's as they require 1.55v. It's very odd because you can put 3.2v through the ram (which is more than enough for most)

It is a stable board a seems to run perfectly well but it does have some quirks.

1. needs more voltage options.
2. can't run 1t above @ 235Mhz (not really an issue)
3. when overclocking you must go up in small amounts 5mhz at a time or it will crash. Even if you know say 225fsb is good, you cannot just set it to this, you must go up in 5mhz jumps from 200 or it will not like it.
4. I used bios 0206 which seemed to give best stability and overclocking. The 2 newer bios's seemed flakey imho

As for the ram I'm not sure - go to the asus site and download the manual. Also do some googling on this board to make sure you know what it's limitations are before trying to get that 146 at 3Ghz.

My board arrived today (building my 1st desktop {check sig for specs} scan delivered on time as expected, ebuyer havnt, grr, but should hopefully get to put it together tomorrow)

This is a direct quote from the manual

"The motherboard comes with 4 184pin DDR400 DIMM sockets.

You may install 256,512,1gb unbuffered ECC/non-ECC DIMMs using the memory configurations in this section

when using only 1 DIMM, install it into DIMM_B1
for single channel memory configuration, start installing the DIMMs from slot DIMM_B1 or B2
For dual-channel memory configuration, install the DIMMs in slots B1 and A1; install another pair of DIMs in B2 and A2
Always install DIMMs with same CAS latency blah blah

Recommented memory configuartions
single channel - DIMM_B1
dual-channel - DIMM_A1 + DIMM_B1
dual channel - DIMM_A1 + A2 + B1 + B2"

Thats all the information i can find in the manual, dont think it answers your question but hope its of some help
