64, ASUS deluxe, Mushkin OCing results...final thoughts

first, my rig:

A64 3000@2.10
ASUS SE Deluxe, latest BIOS
Mushkin 512 3500 lvl1
9800 pro@415/370
antec truepower 430W

For a week I tried to get a stable OC at 2.15, because I wanted to take advantage of my 433 RAM. I tried upping the Vcore, the DDR voltage, memory timings; the best I could get was prime95 not failing for about 6 hours, but i would still get random reboots. So finally I went back and turned everything back to auto, raised the HTT to 210 and so far prime95 has been running for 12+ hours.

My question is, how are people getting higher OC results? I used memtest so i know my memory is good, and from what i've seen my rig should be able to get 2.15 without reboots. should I be concerned that something is not working fully, or is there just a level of variance with hardware components reliability?
 
We're lucky. Because you have the exact same set as I do except I use corsair.

You can try a divider and see if that helps. But een I face some instability issues with my 2.2 overclock. 220 HTT is actually a bit of a stretch without some PCI/AGP lock.
 
hmm...but how can my memory be the culprit if i can run memtest all night without an error OCed at 2.15?

More than likely it's not. It's your PCI/AGP bus. And even possibly your hard drives.
 
I can only get 210-213 with 2 sticks. I got 218 with one stick. But I also use Hyperx. And my AGP or PCI bus could be stopping me (I have a SCSI card, they are infamous for not liking the bus out of spec)

210 is fine. You still get a 5% speed boost free !! And its fast enough.
 
I'm waiting for Epox/Abit/Asus Nforce 3 250GB boards before I make the A64 jump. But anand's 246MHZx10 with the MSI board is truely amazing. I'm plan on using OCZ PC3200EL Platinum 1GB with either a Enermax 460W or Fortron 530W PSU and a TT-Silentboost. Hopefully I'll hit the magical 2.4GHZ barrier.🙂
 
thanks for the input guys...sounds like its out of my hands. I thought Mushkin was good OCing RAM, but it sounds like corsair and kingston are better. something to think about next time i suppose (although this rig should last many years)

Regs, you think it could be my WD 1200JB hard drive? Is there a way to check and make sure my hard drive is running as it should?

Hmmm...seems like you aren't reading it all correctly. 🙂

Your ram should be fine if it passes memtest. Like everybody said it's your pci/agp bus that is preventing you from going any further. The VIA chipset on that board does not have a pci/agp lock...and that is more than likely what's causing the instabilities in your setup. Is your drive SATA? I believe the SATA controller runs off the pci bus doesn't it?

I have the same Mobo, the 3400+, two SATA drives, 1GB Corsair pc-3200, and stock HSF and I am running 220 stable, nothing has happened to it since I have had it, about 3 weeks. My SATA runs great, they are in RAID and with the OC I have had no problems. I don't have anything in any of the PCI slots, that might have something to do with it.
 
there isnt enough difference between 2.1 and 2.15 to justify a new mobo.

last question: would tighter RAM timings improve stability? my mushkin 512 3500 lvl 1 has been running at 2-3-3 through the whole OCing process, and the only adjustment I ever made was to up the voltage from auto to 2.7, which didnt help. so now everything except CAS2 is on auto. I am not familiar enough with the 10 or so options in my BIOS to play with the timings unless somebody knows a good setup for mushkin lvl1.
 
actually, the only thing I have in any of the PCI slots is a SPDIF i'm not using. would taking that out and only having the 9800 pro installed improve stability when OCing?
