** The Official ASUS P5N-E SLI & Ultra 650i Thread **

Memory problem....

Hey guys,

Have been fiddling with my clocks since earlier in this thread and now have two OC profiles that I am happy with:

Profile 1: CPU @2.8G for general family usage

Profile 2: CPU @3.2G for my Gaming.

Problem on both (or stock)is that with my Mem on auto it gives me Arse timings of 5,5,5,32 (i think).

This is my mem: http://www.ocztechnology.com/products/memory/ocz_ddr2_pc2_6400_platinum
When I try to set the clocks to 4,5,4,15 it fails Orthos within 10 secs. Can anyone help out?

Also when I boot the machine the task manager is blank on the Processes tab under User Name... this seems to make things unstable.

Machine as below running 0401 Bios.
Will try and get a pic of the task manager.

I hate it when threads get massive, its near impossible to crawl through everything and get info :p

Will be looking to get one of these boards anyway and a E6300 or E4300, depending what ram Im going to get.

I think it will be on water so the vdroop mod might be a 'must'.
 
Is cpu-z just a bad place to check the vcore? As mine right now underload shows 1.213, and it should be set to 1.5. I know about the droop issue, but that's some droop!

while we're on the topic of voltage readings are there any progs that read vdimm off this board?

What you need to remember is that the voltages are measured by chips on the board. All the programs that read the voltages read the values from the same monitoring chips. So they all give the same values. Speedfan et al allow you to adjust those readings as different BIOS's have different ways of displaying the readings from the sensors but the botom line value is the same. The only way to truly read voltage values from the motherboard is with a voltmeter.
 
I wasn't suggesting that anyone actually do it, although anyone confident enough to be working inside a live PC deserves everything they get if they short it out :p

What I should also have said is that the voltage monitoring chips read values linearly therefore If you have asked for 1.3V in the BIOS and CPUz reports 1.2V, if you set 1.4V in the BIOS it will very likely read 1.3V in CPUz as the base number is out of true, but the relative increments are read correctly.
 
Can anyone figure this out for me. I have gradually overclocking my e6300 in small steps (increments of 7fsb or 28qfsb). I got to 366fsb a few days ago but it would go any further (orthos producing an error after a few seconds) despite ramping up the vcore to 1.45.
Last night I decided to forget smaLL steps try and get it to run at 400fsb, set vcore to 1.35 and offset to +100mv and everything worked fine (no errors in orthos after several ahours and no stability issues with BF2142 or Supreme Commander). My temps were a bit high 63 on load (Coretemp)so I started to knock down the vcore. I am now down to 1.3 +.1 and evertything still appears stable with my temps now 56 on load.
I have heard of poor stability with the DS3 between certain FSB ranges but never heard of it with this board.

I think the information is there, it's just not that obvious. There are certain QFSB numbers or combinations of RAM/CPU numbers that just don't work. Minstadave reported a few posts back that he couldn't run Windows at 3.4GHz, but he could at 3.6GHz. When OC_A64 was first pushing the boundaries of RAM (about page 10 I think) it was noted that you needed to avoid numbers ending in 0 to get a better chance of it running stable.

Everyone that gets an overclock adds to the pool of knowledge, so basically, post your settings please. And well done.
 
I always uppped my qfsb so that it ended in either 2, 4 or 8 and never used 0 untill I put in the 1600qfsb. I had almost given up on it because the vcore of 1.45 was causing heat issues.
Out of interest WJA what motherboard temps are you seeing, mine is at 47 according to asus probe which seems a bit high. I stuck a heatsink on the s/b (I believe this is where the m/b temp is read from) but it makes no difference.

Linked or Unlinked?

32 at the moment from ASUS Probe. IR Thermometer says 27 on a 1cm dot in the middle of the southbridge chip (cool to the touch). Room temperature is 18C. No fans. My NB, HDD, CPU and SLI GPU cards are all passive water cooled so the only heat source is the RAM and the PSU. Silence is golden.

I'm running F@H 24/7 - E6600 at 3.6GHz (450x8) linked with 1.4V+100mV on the CPU, 1.748V on the Northbridge and 2.257V on the RAM (Patriot PC5300 - Micron chips). It's running Vista Business with compatability-hacked XP Pro drivers. It's Orthos Gromacs stable no problem, but it won't run Orthos Blend for more than a few minutes, which probably means I've not got enough voltage on the RAM. As the OCZ water cooled RAM is so cheap at the moment, I was thinking about getting some of that to try instead.
 
Unlinked at the moment. I thought it was easier to just worry about overclocking the CPU at first as the memory runs fine at the speeds and timings below.
Would there be much benefit from linking them?
Memory at 800 4-4-4-12 at 2.085v (Geil 6400C4)
n/B at 1.5xx (Passive Thermalright HR-05 fitted and still gets toasty) although might drop this down to 1.3 and see if it effects stability.
I am surprised at my m/b temp as the s/b doesnt feel that warm

I don't really know. If the RAM will do it, then it seems crazy not to run the RAM as fast as the CPU will allow. I only ran linked once or twice. In this particular configuration it gave the best, most stable results.

I think some of these sensors are somewhat less than useless. My water cooling sensors are calibrated using ice-water and boiling-water so I'm pretty sure they are correct, but they are nothing like the readings I have had from any on-board sensors. They are linear with CoreTemp though, so I'm hoping that the in-die sensors are reasonably true.
 
You have a good point there. 425fsb is the crossover for this board.
Timings on the NB change then and the mobo will actually force a hard reset if you pass that number in the bios
Im at 3.15ghz but I swear Ive had it at 3.6ghz and this is probably the reason why. Thanks for reminding me, I might try skipping it upto a few mhz past 425 and seeing if I have any more sucess rather then edging it up slowly

47 on the MB is too high I think, try better case fans? Not sure if WJA has the side off his case maybe. 63 on coretemp is fine imo, I run upto 70 with no problem
