Overclock my processor .for me

[mramd64]

I am a complete newbie to overclocking and i'd really like some help. This is my system.

MSI k8n neo4
a64 3200+ venice
1 gig corsair value ram 2.5-3-3-8

All i want out of the deal is a 3500+. Could someone tell me in very specific terms exactly what settings they would use as far as hypertransport speed, memory speed, and cpu multiplier for a 200 mhz overclock?

sure, just give me the network password to your computer

check out the stickie on this forum

Change your system bus speed to 220MHz. If that isn't stable, increase your CPU voltage in the smallest increments and check for stability after each increase.

Also set your LDT multiplier (AKA HTT multiplier) to 4x (the default is 5x).

 

[mramd64]

Yeah, I know setting the bus speed to 220 will get me to 2200 mhz, but then what do I do about my memory. Running 1:1 would probably not be possible with my value ram. I've read about memory dividers, but I'm not real sure how to use them.

 

[SrGuapo]

There should be a setting in the bios where you set a divider. Most bioses (at least mine) will have you set the max speed realitive to 200 MHz (133, 150, 166, 183, etc.). A 166 divider means 166:200 or 5:6.

220 MHz seems kinda low. Why not try 240 with a 5:6 divider... That will keep your RAM at stock and let a better OC. Those venice cores should easily be able to handle that at stock voltage...

All you need to do is up the HTT to 240, lower the LDT (HTT divider) to 4x, at set a 5:6 divider. You should be set...

what he^^^ said...

 

[mramd64]

I'm really wary about damaging my system. Do you think my proc will be able to handle 2400 mhz on stock cooling? I know every chip is different, but in general? Also, I can't find any memory divider settings on my mobo. Anyone know what it might be called on my board? There is a setting that allows you to set an artificial clock for the memory.

 

[mramd64]

Ok, here's what I did. I moved the bus speed to 220, lowered the HTT multiplier to 4x, and then I set that arficial memory clock setting to 180 instead of 200mhz. Cpu-z now tells me that I have a 2200 mhz proc and 200 mhz memory. The only thing that bothers me now is that my hypertransport is now only at 880. Does this make a big difference in performance?

 

[jpeyton]

Nope.

Change the articial memory clock to 166, and set HTT at 240mhz. 2.4ghz is a small overclock for the Venice chips, and will be fine with stock cooling. Even if you have to bump the CPU voltage(most likely won't have to) it is still fine on stock cooling. As long as your temps under load (Prime95) stay under 60c your great.

Moderate overclocks on stock voltage or a small voltage increase, poses absolutely no risk to damaging your CPU

 

[mramd64]

Alright thanks for everbody's help. I think I'll try for 2.4. This overclocking is pretty sweet. Better than a 3500+ for 190 bucks!

 

[IamTHEsnake]

Now you see why so many people here practice overclocking. Extra performance for $0 more.

If your good, lucky and know what you are doing, it is possible to get up to 50% more performance.
i.e. Taking a 3200+ from 2.0Ghz to 3.0Ghz.

Very sweet, I'm running my 2.2ghz chip at 2.8ghz FX-57 speed

 

[KoolDrew]

Read the sticky and push it past 3500+ speeds.

Gambateyaro!

 

[mramd64]

I'm now at 2.4 ghz on stockvoltage and it seems to be stable. I still have to run prime95. I'm at 240 fsb, 4x HTT multiplier, and 166 memory divider. Does overclocking decrease the life expectancy of a chip?

 

[GuitarDaddy]

On stock vcore no! Theoretically as you increase voltage it decreases the life, but the life of a CPU is way longer than the usefull life anyway. I have 2 CPU's that are over 20 yrs old and work fine, but have been technologically obsolete for 10yrs or more. I have a an old tbird CPU that has been running strong for 5yrs now on +10% vcore and shows no signs of dying. Even with increased voltage your chance of killing a CPU within its usefull life is slim to none.

Unless of course you give it crazy volts like 1.65-1.70 then you can kill it pretty quick, but only a few boards will allow those voltages without hard modding the mobo.

 

[theMan]

just keep the voltage below a 10% increase aka 1.55v

 

[Vegitto]

About those voltages. What kind of voltages would you guys recommend if the processor would be bundeled with the power of phase? 1.7?

 

[theMan]

with phase, you just go as high as you can boot the machine i would assume. maybe up to 2.0v!

I just began overclock testing today based on Zebo's guide in the sticky and here's what I've got so far.

Max HTT (cpu and ram out of equation) = 330 (ran prime95 for 30 minutes and no errors)
I stopped at 330 because it was pointless to go forward LOL. This was at x3 LDT multi also.

Max CPU (ram out of equation) = 2.75ghz (305*9)
I had it at 275*10 but I figured why not drop the multi to 9 so I can get more FSB. I tested 280*10 and 310*9 both yield 2.8ghz and I could boot into windows but as soon as Prime95 started it's tests it would fail. BSOD. So I dropped back to to 2.75 and so far it's running fine. Going to run Prime95 for 12 hours to make sure this speed is rock solid.

Then I will proceed to test my max memory. Working well so far.

Temps running at 100% load Prime95:

CPU: 40C
MB/Case: 33C
Chipset: 45C
Harddrive: 29C
ACPI: 40C

System specs:

CPU:A64 3200+ Venice
MB: Asus A8N nForce4 SLI (non-deluxe)
RAM: OCZ 1gb (2x512mb) dual channel DDR400 2.5CAS
Cooling: XP-90C heatsink w/ Panaflo 92mm H1B fan attached ; Panaflo 120mm rear exhuast fan ; Panaflo 92mm H1B side intake fan ; Stock 120mm front intake fan

Case: Thermaltake Soprano w/ side window


Talk to you guys in a bit!

 

[mramd64]

If my chip is a 2.4Ghz, I basically have a 3800+ now, correct? Or does changing the Hypertransport speed and fsb make it yield less performance than an "actual" 3800+. Also my temps are about 32C idle and 50C when running prime95. Sound pretty good?

 

[blckgrffn]

You are right on track, congrats Actually, you are right at 3800+, as your memory is running right at spec and teh HT frequency seems to have absolutely no effect on performance.

Remember if you go much over 250HTT to reduce your ht to 3x
do burn in your system before you go further
run those tests
looks as if you are good to go
looks as if no problems with the other two gotchas- pci/agp locks and SATA connections not being locked
you do have a copy of your bios on a floopy?
bios upgraded
hard drive backed up?
congratulations

veggie- you're in the wrong thread
maybe even wrong forum
