Hi,

I use :

AMD Athlon 64 3000+ Venice 1.8 ghz prosy
ASUS A8n-e Mobo
transcend 2x512mb ddr 400 ram
BIG geforce 6600 gfx card with 256 mb VRAM

I wanna overclock my prosy. I dono anything abt overclocking. So, please help me out.

Here Is the detailed Summary of my system(CPU, RAM, mobo, chipset, bios n GFX card) :



BTW, I checked my bios. I dono how 2 handle with OC as iam a newbie. Think there are 2 menus where the overclocking takes place, the dram submenu in the cpu menu and the jumprefree setting menu. so, Which 1 to handle with?

Things in Jumper free configuration :

OverClock Profile - (AUTO, manual, standard, A.I.O overclock, AI N.O.S) Auto is the default option. To which i should change?
OverClock option - disabled
N.O.S Option - disabled
cpu frequency - 200.0
pci express clock - 100 mhz
ddr voltage - auto
cpu multiplier - auto
cpu voltage - auto
pci clock sync mode - auto

Wat are the other info required?

Please help me how to OC in step by step manner. :cry: :cry: :cry:

I tried OCing my CPU n here is the result :

multiplier - 9x
DDR voltage, CPU voltage - auto

First changed cpu frequency to 220 - It was stable
next changed cpu frequency to 230 - It was stable
next changed cpu frequency to 234 - Not stable

Check out the AMD OC Guide in my sig, it's very extensive and should answer any questions you have. Read it, work with it and come back when you hit a wall.


Welcome to OCN!
 
#3 ·
^^^ thanks a lot man


Now here i go:

I OC to 9x250= 2250 @ 1.500 V and my system is stable. CPU temp normally stays @ 40-44*c and on load it goes to max of 55*c, is tis normal temp?

Should i go further? As here @ my place, in summer its very hot

Please check out my settings in BIOS that are related to OCing :

Are they correct???

Doubts :

Why should Hyper Transport Frequency set to 3x???
Wat r those untouched values in DRAM Configuration???

Wat should i do next????
 
#4 ·
The HT frequency is set to 3x because that times your CPU frequency equals your HT speed.... and on a socket 939 board like yours, you want to keep the HT speed at 1000 MHz or less. The untouched values in your DRAM configuration are your ram timings.... you can leave those where they're at until it's time to adjust them. And the memclock index is set at 333 to keep your ram speed down because that will increase as you increase your CPU frequency. How long are you running Orthos to test for stability? And keep an eye on your load temps while testing....I'm not sure about your CPU, but I don't think 55C is too bad for load temps on that one.... what are you running for a CPU cooler?
 
#5 ·
I am using stock cooler, I use everest 2 check temperature

I ran the test for nearly half an hour using orthos n here is the result :

You could slowly increase your CPU frequency.... maybe 2-3 MHz at a time, but no more than 5 MHz.... raise it, then test for stability. If it is stable, then you can give it another little bump.... just go slowly.... OCing takes time. Good luck!
 
#7 ·
A quick note as well. You really should try to keep that Venice under 50C if possible but with added vcore and a stock cooler that may not be possible. If you don't have any $ to spend on a better cooler than I would advise that you don't add any more vcore. I don't mean to add a plug for myself but I do have a used Thermalright XP-90 that I used on my socket 754 Venice and it did a great job, that being said it is just sitting on my desk right now looking for a home. If you are interested in buying it or anything PM me.

Keep us up to date on your progess.

Navino, have you tried finding the limits of each component yet? Please check out this guide when you have a chance and try the process out: http://www.overclock.net/faqs/31782-...pu-memory.html. You may not actually need that much voltage. How high were you able to clock the processor at before you need to start adding voltage changes? What is your HT multiplier set at? Settings that you want to look for in regards to that should be 1x, 2x, 3x, 4x and 5x.
I just recently tried pushing a 3000+ Winchester but I couldn't get it passed 2.5Ghz stable. Seeming you have a Venice core you should have a some what easier time playing with it.

Good luck

Officemac, looks good! If you try and go any higher let us know how it goes

Bumped it up to 250*9 and its gone through about 30 minutes of prime95 like a champ. I wasn't able to get it over 235*9 but I replaced the ****ty thermal paste with AS5 and its running real nice now. with the stock cooler too. Vcore is at 1.38. Temps are about 50C at 100% load. This OC's way better than my x2 6400 BE.

OfficerMac, sounds like you still have plenty of OC'ing room. How is your memory at your 250TT * 9x overclock? Those temps look great. The clock speed of the 6400BE is already at the limits of the K8 tech so that would explain for the "not so high" overclock.

I hope to god you are referring to the bus speed and not the overall chip speed....

OP: Venices can be a bit of a PITA to OC. Mine will go only 300mhz and then hits a wall. 2.7, and that's it...then again, I haven't thrown 2 volts at it either...not that I want to


As for your temps, as long as your mobo's safety shutoff is 65C you should be ok, but I wouldn't want to be running a Venice that close to shutoff for more than the hour it takes to figure out why it's running so hot...They tend to, um, die if allowed to run much above 70 for more than a few minutes. They don't like it at all.

CPU FSB : 278.5 MHz (stock : 200 MHz, overclock: 39%)
HTT : 278.5 x 4 = 1114.1 MHz
MemoryBus : 227.9 MHz , (333Mhz in BIOS)
DRAM:FSB Ratio : CPU/11

Memory Timings : 2.5-3-3-8 (CL-RCD-RP-RAS) , (CR=1T)

Regarding Voltage :-

CPU Voltage : 1.425V
DDR Voltage : 2.90V

Benchmarked by Torture testing with Prime95 for 8 hours & 30 mints Flawlessly.
Cpu temp stayed at max of 52' Degree. Never above that. May b i hav a good air flow inside my case

JamY, looking good


That is some decent memory you have there. Have you tried pushing it your processor overclock anymore? If you get close to 300HTT try giving the chipset more voltage, that should help you if you have any instability issues. Make sure you have sufficient cooling on your board to handle the new voltage changes.

Good luck

Thinker, i cudnt find any voltage settings on ma mobo for the chipset
Regarding voltage plz c ma previous post (hav edited that). And iam confused bout '300HTT' in ur reply abov
Actly did u mean 2 say 300 cpu fsb????? . Coz in ma mobo i can only multiply the CPU FSB with HTT (i.e for eg: 278x1 or x2 or x3 or x4 or x5 or Auto) to get a certain value in Mhz.
ya i hav tried to push the fsb to 280.., but failed after benchmarking[Torture Test] for 3 hours & 30mints
. Even i hav tried the same test after pushing both Cpu core & DDR voltage, but even then there was no use at al.
.
.
.
So thinker., plz think nd gimme suggestion if u hav got some..

JamY, to adjust the cpu voltage (Vcore), go to Advanced -> JumperFree Configuration. Look for "CPU Voltage". The HTT (reference clock or FSB) can also be adjust in that menu. Check "CPU Frequency".

Have you had a chance to read over any of the guides I posted above? When you have time check them out, it should shed some light on a fe wof your questions


Good luck

think3r, i got realy confused when u wrote "chipset voltage" in ur previous post. Actly u meant 2 say was "CPU CORE" voltage i guess
. Well, I hav even tried by pushing it from 1.4v to 1.5v. But it cudnt come up


yes, hav gone thru all those helpful sites, but i cudn't find a new trick 2increase ma FSB inorder 2 get a Stable results


Down here it goes Ma Oc'ed Rig Details :-


And thankx 4 ur reply..
 
#24 ·
Jamy, just by judging by that screenshot you may have to adjust a few things. Try getting your HT (hypertransport) speed below 1000mhz. Right now your at 1114mhz which may cause some problems if you keep raising your HTT (reference clock). Change the HT multiplier from 4x to 3x.
Relax your CAS (memory sub-timing) from 2.5 to 3 and see if that helps. I would also drop your memory to a lower divider. Try and get that memory below the factory 200Mhz. I'd advice tweaking your memory later on after you've gotten your processor stable.

Try those things above and see if it helps

Good luck

think3r.., i hav done as u told. But y the HTT should b kept < 1000 Mhz. wat mi8 b the techinal reason 4 that..??? i wish if i cud noe that
.

by the way i will juz add here the deatils f ma DRAM config :-

memclock index value : (333Mhz) [Shud i keep it in 333 itself..?? or reduce it ?? The minimum is 200mhz]


RAS : 8T
RAS to CAS : 3T
Row Precharge time : 3T
Row cycle time :11T [I shud change the timing here??
]
Row Refresh Cycle Time : 14T [I shud change the timing here??
]
Read to Write Time : 5T
Write Recovery time : 3T
1T/2T mem... : 1T [default was 2T. Shud i change it 2 Default...??
]

Now here goes ma "Jumperfree config" :-

CPU Freq : 278.0
PCI Express Clk : 100Mhz [No idea watz this bout
. Plz help ]
DDR Voltage : 2.9V
CPU Multiplier : x9
CPU Voltage : 1.425 [ Default was 1.420]
PCI Clk Synch Mode : 33.33Mhz [Am i right here??
]

==============================================

Hav Reduced HTT below 1000Mhz. Now itz 835.5 [278x3=835]

So Think3r,,,, NOW WHAT????????????????

Sorry 4 killing ur Time.
And Thankz Again
 
#26 ·
JamY, your not killing my time I'm here to help


Let's clear up a few things. HTT is the reference clock ie 270mhz. HT is the hypertransport speed which at the moment is at 835Mhz. Just thought I'd mentioned that so you don't get confused.

Socket 939 typically likes lower HT speeds preferably below 1000mhz. Anything higher then that and you may run into stability issues. In some rare cases I have seen S939 boards hit 1000-1200mhz but it's not common.

Can you post some CPU-Z screenshots of your current overclock? Include each tab if you can.

At the moment don't worry about the PCI Express Clock. Raising it between 107-112mhz can yield some positive results with overclocking but not always. I'd also recommend dropping your VDimm (voltage for your memory) to 2.6volts. If your memory is not overclocked then kept the voltage close to factory (JEDEC standard is 2.5volts).

Let us know

Good luck
