I want to OC my processor, its only a year old. All my system specs are on the left.....

I want to increase the multiplier speed and aswell a few others.
The heat is ok, In summer my CPU only gets to 38c-43c on full load increasing the speed wont cuse to much more heat. "Will it".

Eventually i will get a new M/B and CPU but i have no money atm so some OC will do for now.

Mainly i want to increase the performance of the Crysis Demo, With a res of 1280x720, No AA, and everything maxed i get 7-18fps. I think its due to my CPU as when in heavy fire fights or exploding building the game goes into a Slow-mo mode. The fps stay constant but it just runs slow.

I mainly want to increase the front bus on the M/B.

So can anyone help me out.

Your in for a tall order my friend laggs alittle maxing it with a 8800 gtx and a 6000+

 

[Aus_Karlos]

Well there are something like 10,000 threads on the web about Crysis and its crappy performance on the 8 Series and DX 10. Most ppl carnt get over 30fps..

Well anyway how do u OC a CPU, i think my BIOS has a whole section with numerous OC settings. But i have no clue what they mean.
If you could direct me to a list with descriptions that would be great.

Ok just have to say you can damage stuff in you system as you know

http://xbitlabs.com/articles/cpu/display/newbie-oc-guide.html

Start out slow

 

[Tumbleweed36]

Start out very slow as mentioned by my team mate 1 g0t 0wn3d. What we mean by that is do a small increment, then use it for a bit to see how it does before you move up. Your worst enemy with this rig or any that you overclock is HEAT. Monitor that closely to prevent damage to system components. Then, when it is stable, move it up a small tad and run it that way for a while until you find a reasonable setting that helps it to perform, but does not put your system under too much stress.

BTW: I love the power supply you are running and it should kick this baby with no problem.

 

[Aus_Karlos]

I will try and OC as much as i can until i think the temp and the CPU is stable. Not to confident about messing with the Voltages so that will be a limiting factor in my OC.

 

[Aus_Karlos]

Here is a list of the OC settings my Motherboard has. Could you guys help me to understand them. The article u gave me was great but there are only 2 things they covered on OC the CPU.

HT Frequency Ratio (Auto)
x1 to x5

CPU Frequency (200)
200 - 400 (i think it goes further)

K8 CPU Clock Ratio (Auto)
x5 - x12

DDR Clock / Timming Mode (Auto)
- CPU / DDR Clock Ratio (2/ 1.66)
- DDR Speed (333) I think i should be 400 as all my RAM is 400mhz

DDR Timming (Auto)
-CAS# Latency (2.5)
- Min RAS# Active Time (7T)
-RAS# to CAS# delay (3T)
-Row precharge time (3T)
-Row to Row delay (2T)
-Row cycle time (10T)
-Row refresh cyc time (20T)
-Read to Write time (4T)
-write recovery time (3 Bus Clock)
-Read to write delay (1 Bus Clock)
-Refresh rate (166mhz, 7.8us)
-Read Preamble Value (6ns)
-Async Latency Value (7ns)

CPU Spread Spectrum (Center)
Disable

Robust Graphics Booster (Auto)
Fast, Turbo

Long list i know.. But any help will be great.
Like i said i would like to increase my front Bus speedas i heard there is the most performance to gain there without too much cost..

read thru this several times then we can get started


http://wiki.extremeoverclocking.com/wiki/Athlon_64_Overclocking_Guide


http://www.overclock.net/amd-general/91-ultimate-overclocking-guide.html

 

[Aus_Karlos]

Ive read them but. How do you know what the Default speeds are. All they say is (Auto)..
Well my current Core speed is 2400mhz so that could indicate. Core Clock of 200 and HTT Multi of 11.5 or 12.5.
And my current RAM timming is 2.5-3-3-2 (is that good or could be better)

 

[1 g0t 0wn3d]

ok the multi multiplyed by the core clock is your cpus clock so if you up your core by one then your cpu will go up aorund 12 mhz with that multi

 

[linderman]

Please download cpu-z then give us your screen shots of cpu-z main tab and the memory tab

http://www.cpuid.com/cpuz.php


this adventure is not a fast one; unless you want to risk some wasted parts $$$$


if we proceed slowly then you will enjoy the ride ray:

 

[Aus_Karlos]

Ive taken the liberty of screen shooting all of the CPU-Z tabs.
Ive noticed that in the SPD tab memory Slot 1 and 2 can go slower than 3 and 4. And that the timmings are differnet. I bought the all 4 RAM sticks from the same place at the same time strange that they are different. Will this effect my OC?








Also i want to take my time and go step by step i dont want to have to fork out $$$ as im very limited atm. Altho Cooling will take priority and will spend money for that.
Also i want to start OC Friday or saturday cuse of my work. So take your time aswell.

 

[HawMan]

:grin:Just as a small guide ive got my 4600+ to 2.7 on stock cooling. The temp doesnt go past 55 on load.


The FSB is set to 225Mhz but for it to boot i had to drop the HT to 600mhz. ( Do all of this in the BIOS ). Overclock it small bits of at a time then run Speedfan/sensorview and use orthos to stress out the cpu.


I dont know why your RAM is showing at 160mhz though, it should be 200.


Im Not a overclocker but every little helps

 

[linderman]

OK to get started I would as follows




you must get your ram frequency to 200mhz instead of 166mhz

trying changing it the manual settings (bios)

I always bump the memory vdimm voltage to 2.75 (this is still within warranty by most all ram makers)

then set your HTT to 4X


try these settings then post new cpu-z shots

 

[Aus_Karlos]

Ok ive put the HTT multi on x4 (HTT link gone from 1004.5mhz to 804.8mhz) but the RAM is still on 160.8mhz even tho ive increased it to 200mhz on the BIOS.

 

[Aus_Karlos]

Edit: Ive just noticed something i havnt noticed before. When i drag a window or play a game the dark areas of a picture are in 256 colour or somthing. So for now im resetting the BIOS back to its default settings.

Also if i look really close to the screen its full of noise.

 

[Aus_Karlos]

Ok i tried reseting the BIOS back to default and it no longer boots or POST or does anything. Ive reset the CMOS by the jumpers ect ect.. I think the problem is a faulty motherboard. The Description gave above has happened to 2 other GPU's ive had. The odds are so great that i have managed to get another faulty GPU.
As i have turned off my PC straight away i hope i havnt damaged my Brand new GPU, what do u guys think, do u think my GPU is fine.
Im hoping its the motherboard as ive spent $800 so far.

I would say your memory is holding you back from achieving top performance


I would get and install two one gig sticks of DDR2-800 Corsair memory with 4-4-4-4-12 timings

then sell off your old sticks on ebay


your leaving alot of performance and FPS behind with your memory set at 166mhz

 

[Aus_Karlos]

Thinking of Buying.
$279

$244

Can you tell me if this is all compatible with each other and my current h/W

My current M/B that is broken only supports DDR
