OCed 3800+ X2, opinions, suggestions please!

post #1 of 6
Thread Starter 
Okay, I'm stable on the CPU test for 11+ hours on Orthos. I recently set the divider back to CPU/10 (1:1) so my memory will at least clock to specification. I haven't been able to figure out why I can't set the divider to CPU/11, because when I select the next memclock mode in the BIOS, it sets to CPU/12.
My current divider allowing me to achieve these clocks is called DDR400 in my BIOS. I know that there is a way, just can't figure it out :\\
My PC has been stable at 260 HT for 1.5 hours on Orthos, but I stopped it to reboot. If anyone has suggestions, please let me know!




Also, there are some settings that I am wondering about in my BIOS, such as:
32-bit DRAM memory hole: disable/enable
MTTR Mapping mode: Continuous/discrete (not sure about discrete, can't remember LOL)
Bank Interleaving: I know that 4-way can provide better performance, but that's all I know

Some BIOS allow for more DRAM ratios, for instance my DFI allows 5:4, 1:1, 5:6, 3:4, 2:3, 1:2 and probably a coupe more I forgot to add.

In CPU-Z it measures the ratio in regards to CPU freq. but in the BIOS it usually measures it in FSBRAM freq. Or sometimes it will be a 'rated' speed, for instance my old ASUS board had RAM dividers of DDR500, DDR400, DDR333, DDR266, and DDR133 (which is 5:4, 1:1, 3:4, 2:3, 1:2)

I hope this clears some stuff up. Also Bank Interleaving does improve the performance of your RAM with some loss of stability, try different settings for more stability/performance as you see fit. I have no clue what those other 2 settings are, however. Sorry.

Also, if that is TCCD RAM, you could get tighter timings with DDR500 speeds such as those, and if thats BH-5/6 RAM you could stand to go EVEN tighter depending. But its a goos start.

Look for you'r max OC in the cpu.First then worrie about you'r memory later.And that's why you want to use divider's.Take a look @ some of the guides in the memory section too.http://www.overclock.net/faqs/31782-...pu-memory.html

Yea, so far my max HT speed is 260, and I will try higher. The thing is, I can't even boot when I'm using dividers. I already read that OC guide!
I can't seem to find spectrum spreading in my BIOS either. Yesterday I was running Orthos at HT=270, and I was getting waaaay hot temps, but now I have replaced the POS fan on my Arctic Freezer 64 Pro with a Silverstone FM92, so my max temp @ HT=260 when running small FFTs in Orthos is 54C according to the amd core diode (in Coretemp).
That being said, I really doubt that I can achieve a higher FSB than 270 that is totally stable.
Oh yea, I'm going to lap as soon as I get some extra time (HS only.) Also, I am going to crank up the VCore by another 0.025 (wutup Beret ) BTW, I have active cooling on the RAM modules, and also some copper RAMsinks on the mobo VRMs. I also have some Evercool copper RAM coolers, but I don't know if I can get them to fit onto these heatspreaders....this really doesn't matter yet, as I'm only at spec clock!
Oh yea, what about the Northbridge voltage? I just got an error in Orthos after 4S on the blend test.....***? This is 10 MHz lower on the HT than when I ran CPU only for 11+ hours!

LOL oh yea, CPU-Z is misreading my voltage: it is at 1.40V! (Vcore)
The only settings for dividers in my BIOS are the DDR settings, which sucks because I have to set the DDR setting, then check the numerical value in CPU-Z, then extrapolate the value of my OC that I'm shooting for, thus calculating the memory clock. ABIT ***! MicroGuru is a very convenient app, though! I can set what I want while I'm on forums and stuff.
