Overclocking my CPU

[kaitlin4599]

hello im trying to overclock my cpu and i read some where that i might have to lower my ram or its timings to get a stable overclock im using an asus m2r32-mvp mobo with an AMI bios so what do i do to the ram so that i get a stable OC

What RAM do you have?

The timings/speed will be available in the BIOS. I don't have time to look ATM, but your manual will show you how to adjust this.

I would lower the speed if you are running it currently at its rated speed. The timings really aren't worth messing with, IMO.

im running 4 gigs of ddr2 2 1 gig sticks of corsair 6400 ddr2 and 2 1 gig sticks of supertalant ddr2 heres the info from speccy

Type DDR2
Size 4096 MBytes
Channels # Dual
DRAM Frequency 334.1 MHz
CAS# Latency (CL) 5 clocks
RAS# to CAS# Delay (tRCD) 5 clocks
RAS# Precharge (tRP) 5 clocks
Cycle Time (tRAS) 15 clocks
Bank Cycle Time (tRC) 21 clocks
Command Rate (CR) 2T

also im using the bios auto overclocking utility i have the overclock set to auto instead of manual for my cpu

Well, since the Corsair are 800, and assuming the Supertalent are the same speed (do you know for sure what the speed is?), you have some decent headroom as-is, since they are running 667 now (according to the data in your post).

Have you tried some overclocking yet?
What CPU do you have, and what cooler do you have it?
Make sure you are monitoring temps, mainly under load.

The timing is nice for 667.if they are.and overclocking them will not make a big change.and as mention by Ketchup.what is your cpu.

sadly my cpu is a phenom 1 x4 9500 i know its an old cpu but its the only cpu i have and i cant afford any upgrades im poor and i got this cpu for free also im using an amd heatsink with copper pipes heres a link of the heat sink im using

i dont want to overclock my memory i want to lower my memory so i can give my cpu more headroom when i overclock it all 4 sticks of memory are ddr2 pc2 6400 1 gig per slot for a total of 4 gigs

OK lets start with all your system spec.

 

[kaitlin4599]

heres my specs

ASUSTeK Computer INC. M2R32-MVP mobo
4.00GB Dual-Channel DDR2 @ 334MHz (5-5-5-15) ram
xfx ati 4890 1 gig pcie gpu
sata 1 gig HDD ide cd rom
OCZ 600watt psu need any other info let me know
Phenom X4 9500 (HD9500WCJ4BGD),2.2GHz,rev.B2,95W,SocketAM2+,Quad-Core CPU
oh and my os is xp pro 64 bit

I don't it's a very good ideal to lower the rams.and overclock the cpu.in that case i would ask a mod to move your post in CPUs and Overclocking

You could potentially lower the memory clocks even further to the last rung ~

Memory Timings

1. @ 400 MHz 6-6-6-18 (CL-RCD-RP-RAS) / 24-51-3-6-3-3 (RC-RFC-RRD-WR-WTR-RTP)
2. @ 333 MHz 5-5-5-15 (CL-RCD-RP-RAS) / 20-43-3-5-3-3 (RC-RFC-RRD-WR-WTR-RTP)
3. @ 266 MHz 4-4-4-12 (CL-RCD-RP-RAS) / 16-34-2-4-2-2 (RC-RFC-RRD-WR-WTR-RTP)

I have overclocked my system by 30% with memory at 665MHz & manual timings of 4-4-4-12 so you'll have to see if you're mobo supports these options or not but I think it does.

what's your current OC? Start with everything at stock settings and see how high you can push the fsb before thread fail in Prime95.

 

[kaitlin4599]

my problem is that i cant lower my multiplier or adjust my voltage in my ami bios as asus has thoes options greyed out ill test with prime 95 later on today and report back

 

[kaitlin4599]

also should i dissable the TLB bug fix since my quad core has the TLB bug update i had it at 2.3GHz and it crapped out im thinking i should go back to my old dual core 6000+ 3.0 cpu untill i can afford an upgrade as im having alot of problems OC this cpu

Yeah, I think your CPU is lock multiplier. You have to use the front side bus (FSB) to overclock it. That's where having the correct memory setup becomes important.

 

[kaitlin4599]

ran prime 95 for an hour on the blend stress test with an overclock of 2.3 Ghz and results said it passed that was with the multiplier at the stock 11x because i cant lower my multiplier in my bios also voltage was stock

 

[monkeydelmagico]

keep increasing fsb a few at a time and re-test until a prime thread fails. Then bring it back down to the last good value. See what it gets you. I'm guessing somewhere around 2.6ghz.

If you want/need to go higher then it starts to get more complex. Like others have mentioned, you will have to start working with memory settings and timing, keep close eye on NB settings, disable C&C if it's even on that board, etc. If you go that route go find an old thread about OC'ing this chip.
