Suggested Settings for Best OC

Hi everybody,
I am new here and would gladly take any advice. I've had a bit of (ease) luck in getting my 45nm to 2.8 but I think that only better CPU cooling will let me go futher. Any advice would be greatly appreciated.

This is my humble rig

VIsta x64 SP2 6002
Gigabyte GA-EP43-UD3L
Q8200 @ 7x400MHz (2.800)
NVIDIA GeForce 9800 GT (512 MB) OC'd @ 720 MHz
2x2G OCZ HPC Reaper @ 800MHz@2.0v 5-5-5-15 2T
Thermaltake PurePower 430-Watt PSU
Dell E228WFP (Digital) [22" LCD] (KU31178D3P5M)
Realtek ALC888 @ Intel 82801JB ICH10
WDC WD2500AAJS-22VTA0 ATA Device (232 GB, IDE)
Seagate External Drive USB Device (111 GB, USB)
Realtek RTL8168C(P)/8111C(P) Family PCI-E Gigabit NIC
2x80mm Masscool
1x120mm Antec TriCool
1x120 Scythe Kama Bay 5.25
Ultra 4 Channel Fan Controller
EVGA Stock GPU Cooling @ 3,400rpms via RivaTuner
Intel C2Q Stock CPU Cooling :(

Software I use:
Using Everest, CPUZ, SuperPI (19s@2.8OC 1:1), HyperPi, RivaTuner, SIW.EXE, Prime95, 3dMark06, Crysis Benchmarking Tool

I hear it can be a pain to swap fans after they are installed. Idle temps are a bit high, 53,52,51,47- 24 (via Everest, Confirmed in Bios and with SIW.EXE) I'm curious as why my "CPU" temp is so much lower than each of my core's.

1:1 FSB:RAM for Stability though I know my ram is capable of being stable at 1120 but after that timings tend to get undesirable, I'm sure with more voltage it could do 1200 as OCZ claims but is it even worth it? It's down to 800mhz for stability. I'm still new to this and would love to learn from your advice. Much Obliged

3dMark06 with current OC

Thanks again!

  1. First get better CPU cooling. Then read the stickies. Then come back with detailed questions.
  2. I noticed your power supply. Please see here:

    The main problem with this power supply is that it can’t deliver its labeled power. It is, in fact, a 350 W power supply
  3. You need to improve your temperatures. Check them with Realtemp.

  4. I have the same CPU OC'd to 2.8ghz too. same 1:1 ratio, at 400mhz fsb.

    First remenber that at 2.8ghz is already a 20% OC'ed, and if you dont have a proper HSF dont OC further, temps can reach 80-85 with stock hsf.

    I have tried 450mhz x7 getting 3.15ghz, at this point it was 35% OC'ed, as you can see the low multiplier does not help at all. Compare this to a Q6600 let's say running 1:1 ratio at 800mhz ram, we have 400x9 = 3600, and that's without OC'ing your ram.

    so in our case, we need to OC the ram in order to go higher, since you have a nice RAM over there, try pushing it and tell us what happens.

    Good luck.
  5. UPDATE:

    Thank you all for your help, I have since upgrade to a OCZ ModXStream Pro 600 W PSU, an Artic Freezer 7 HSF and just for fun I got a core216 gpu. All of this is now in an Antec 900 too, all 4 fans on high.

    Now at 2.92 fsb 417 1.34vcore -fsb didnt want to post at 420 but only tried once and at the one vcore setting
    DDR2 @1112mhz 5-7-7-7-21-76 2T @ 2.2v

    this got me +650 on 3dMark06 here is the new result:

    4x prime95 without taxing my ram gives me temps in the low 60s

    Thanks for your help, always excited to learn more
  6. The only problem is that overclocking RAM does not increase real world performance much.
