cyberlord Posted September 17, 2005 Posted September 17, 2005 Hi, Hi, I just got this new MB/CPU/MEMORY/PSU and decided to pump it up tp 2.2GHz. I increased the FSB to 245 and had memory failures. I increased the DRAM voltage up one notch and it ran for a bit but failed memory tests at about 75% complete. I increased one more notch to 2.8V and it passed the memory test. All the other settings are at normal. I don't run windows, but I've run burnMMX in FreeBSD for 12 hours. No problems noted and I've documented a 22% increase in compile times on my code from stock 1.8GHz. Knowing this information, could I consider my system stable? Is pushing the memory to 2.8V going to kill it? Is there any bootable CDs with benchmark tools on them (3DMark,Aquamark, Everest etc), or does anyone know of any good FreeBSD/Linux benchmark programs? (Edit: I've tried as I said burnMMX and LMBench 1.1, but the output from it is pretty useless as it doesn't recognize the AMD64 chip and gives me a false MHz indication.) Thanks, Tim Quote Share this post Link to post Share on other sites More sharing options...
Vortexics Posted September 17, 2005 Posted September 17, 2005 first of all you need to find out what memory chips are those crucial you got, so on that will depend your memory volts, killing it or feeding it. put the exact memory model.

TheFlowerKing Posted September 17, 2005 Posted September 17, 2005 I'm not completely sure of this, but I can vaguely remember reading somewhere that unix derivatives are harder to get stable than winslows. Quote Share this post Link to post Share on other sites More sharing options...
thegnode Posted September 17, 2005 Posted September 17, 2005 Use a program like sandra to check your memory bandwidth. Inch up your voltage and see if your bandwidth increases or decreases. If it increases, you are feeding it. If it decreases, you are giving it more than it can use. It wont break at that point. Just dont do something like stupid like jump up .5 volts or something.

The memory I have is CT6464Z40B.8T, rated at 2.6V. Quote Share this post Link to post Share on other sites More sharing options...

I don't run Windows, but are there any programs out on bootable CD I could use? I found this ramspeed program that gives bandwidth, now do I increase the mem voltage until there are no increases? Here are the results at 2.8V. Thanks, Tim [root@hercmud ramspeed-2.3.1]# ./ramspeed -b 7 RAMspeed (UNIX) v2.3.1 by Rhett M.

Boppo Posted September 27, 2005 Posted September 27, 2005 I think the answer to your question is if you are comfortable with it as it is, then it is stable. If the computer does what you want it to correctly without crashing it is stable. Quote Share this post Link to post Share on other sites More sharing options...
Gipse Posted September 27, 2005 Posted September 27, 2005 Hi, search for "ultimate boot cd" with google. Nice tools and some stress programms for dos. I think the latest version is 3.3, give it a try. Gipse Quote Share this post Link to post Share on other sites More sharing options...

I think the latest version is 3.3, give it a try. Gipse Yeah, I tried that and it's fine and all, just doesn't have the tools prescribed in this forum. I'm playing with Bart_PE and installing the tools recommended here on it. We'll see if it's feasible. Tim Quote Share this post Link to post Share on other sites More sharing options...
