OCing a Venice 3200+

[RallyMaster]

So my friend comes over and says, "You have all this cooling but you aren't overclocking?"
And come to think of it, I spent almost 120 USD on all these cooling parts but they're cooling stock components.
So now I have my HTT at 220 and can't seem to get it any higher. At 230, CoD2 won't load levels. At 240, mobo won't even POST. Increasing voltage doesn't help much either (I'm still at stock voltage because it seems to be plenty stable with a 200Mhz OC). I've already tried decreasing multis and all those attempts seem to have resulted in the mobo not POSTing. What seems to be wrong? I'm thinking memory because it's ValueSelect but is there some other stuff I'm missing? I have HTT multi at 4x, should I decrease it or put it back on 5x?
I'm not exactly proficient when it comes to OCing. This is my first board that actually deals with all this stuff (unlike my old Biostar Skt A board) and I'm not understanding it.

First off put the htt multi to 3x. Second. Did you use a memory divider? You need to use a memory divider to keep your speed under/around 200mhz on mem. Also timings need some attention. May need to relax those as well. Ive never used value memory in my life so, im not exactly sure how timings and overclocking work with that stuff.

Judeging from you saying youre still at stock voltage. Its probably voltage. Not all venices are the same. Some actually do need more voltage to oc high.

Ok, going to put HTT to 3x. Do I set memory to go by SPD? Or is that not a memory divider?

 

[Fallengod]

No spd is not a memory divider There should be a place in bios that has a setting related to memory that has like "133, 166, 200" etc... You need to use whichever one keeps the speed under 200mhz(the stock default speed for value 3200 memory) The trick is to keep it as close to 200mhz as possible without going over. Because I dont think value memory is going to overclock well.

Thats probably your problem. Although you said you were at 220mhz already. Thats higher than I woulda thought value memory was going to go.

 

[RallyMaster]

so should I get it down to DDR333?

(btw, i'm speaking to you from DDR400, 3x HTT, 230 Mhz x 10 on 1.42V) lemme see what's going to happen if i get into CoD2.


EDIT: nope, crashed at loading a level

 

[Fallengod]

You should use whatever divider that keeps you under 200mhz. Unless your memory actually does do 230mhz.

I'm at 220 HTT and everything is smooth and stable. I crashed at 225 HTT when shooting too much on the Warthog minigun. Looks like I'll be stuck at 3500+ speeds for now. Heck, 50 dollars worth of improvement for free is nice.

give it some voltage!!

 

[RallyMaster]

Haha, I'll be sure to increase it a bit more. I ran 230 HTT at 1.44 but it wasn't stable. Should I go even higher?

 

[Sparky19692]

Sure! have that cooler and 1.6V is still only 47 C. I would try to stay below 1.55 If you can.

im runnin 260HTT on my 3000+ winchester... i know you can go farther than i can.. im even stuck w/ a 9x multi... oh im pushing 2.3Ghz too... and all at stock voltages...

so im at 260HTT, 3x HTT, 219ram@2.7v, 2.3GHz@ 1.45v...
ASRock Dual939-SATA2 mobo and using a gigabyte 3drocket w/ Thermax Themalgrease(that new company from texas) w/ idle of 32C* and full load of 42* but to be fair my mobo is readed a 32C ambient... oh and i have my x800GTO2 running at X850XTPE 535/600 all on a Thermaltake, yes its a pos, Purepower 420watt.

check your 12v levels when underload... mine go from 12.2 to 11.89 under full load and i think thats about as far as is safe conisdering ialso have to spin 2 Optical drives and two 160gb 7200rpm WD drives.

 

[RallyMaster]

for some reason, whenever I change the multi, my comp won't boot (doesn't even load vid card BIOS or POST). what did i do wrong?

 

[RallyMaster]

after playing around, i stuck with 10x multi but increased HTT to 240. 2.4Ghz now at 1.56V. memory running DDR333. how much more do you think i can get out of this thing?

 

[RollWave]

dunno, but I love my A64 freezer. JUST put mine on and temps at idle dropped 14C. Now my load temps from prime are actually lower than my idle temps used to be.

The trick to OC is that you wanna make sure your CPU is the only bottleneck in the system. Because otherwise even before you reach the full OC capacity from your CPU your other parts will come in and stop your machine from working. So name of the game is eliminate bottlenecks elsewhere in the system except CPU. This can be done by making sure all your other parts stay within their limits of operation.

Here's some things you need to do:

1. keep multiplier at the highest level which is 10 for you. THis is because decresing multiplier means you have to pump up HTT, the higher HTT the more you pushing motherboard, you wanna use the lowest HTT to do the job.

2. you need to make sure total HTT is below 1000. This mean if you set HTT multiplier to 3x, Your make sure your HTT itself is below 333. If you HTT is 4x then you can only do 250 or lower. This tells you how high you can set you HTT.

3. You CPU is just HTTxCPU multiplier. So HTT=250, CPU multiplier=10 means a 2.5 result. Now you just incrementally keep rasing your HTT little at a time to reach higher CPU result. At every raise you need to adjust memory to make sure it runs below DDR400. This is done via setting memory speed to lower than DDR400, say use DDR200,266,333. SInce your HTT is raised the reality DDRxxx number will be bigger than your setting in the BIOS. Setting you RAM to say DDR266 don't mean it will run at that speed, since you raised your HTT above deafult 200, that will scale up DDR speed as well. Just choose something so the reality RAM speed is below 400.

Try these procedures at default speed before upping CPU voltages. Once you figure out how to do the OC at default speed then learn to do more creative adjustments at higher voltage. With your excellent cooling, no telling how high you can go, it should be a very good result.
