Questions on general OC idea

post #1 of 2
Thread Starter 
Hi guys, I've overclocked before on older computers, but I've been sorta out of the scene for a couple of years so I need some help. There are so many options lately. Several years ago all I had to set was cpu x multi to OC, now it seems so complicated.

I just recently upgraded all my parts and I had some questions about overclocking theory. I have read through the "ultimate overclocking guide" that is at the top of this forum, but I'm still a confused. I think there's just something obvious that I'm not getting.

For reference, here are the parts that I have for my system:
DFI LANPARTY UT nF4 SLI-DR Socket 939 NVIDIA nForce4 SLI ATX AMD Motherboard - Retail
Panasonic Panaflo FBA09A12H-1AZ 90mm Hydro Wave Case Cooling Fan - Retail
ENERMAX Whisper II EG565P-VE FMA(24P) ATX12V 535W Power Supply - Retail
eVGA 256-P2-N516 Geforce 7800GT 256MB GDDR3 PCI Express x16 Video Card - Retail
Seagate Barracuda 7200.8 ST3250823AS 250GB 7200 RPM Serial ATA150 Hard Drive - OEM
OCZ 2GB (2 x 1GB) 184-Pin DDR SDRAM DDR 400 (PC 3200) Unbuffered Dual Channel Platinum System Memory Model OCZ4002048ELDCPE-K - Retail
THERMALRIGHT XP-90 Multiple Heatpipes Cpu Heatsink - Retail
AMD Opteron 148 Venus 1GHz FSB Socket 939 Processor Model OSA148BNBOX - Retail

I installed the parts, updated the bios, then loaded optimized defaults, set dram core voltage to 2.8V and it's been running stable ever since. The CPU temp is around 33C. I tried running the FEAR demo and the half life 2 demo. Everything is really great so far.

I am planning on overclocking, however, I have a few questions.

1. To overclock, do I really just need to try new FSB frequencies and multipliers until I get the fastest combo I can find that is stable and doesn't go above 50C? Or are there other things that I need to touch in the bios?
2. This goes along with question #1. How do you know when to change the timings of your memory? How do you know what to change it to?
3. This goes along with question #1. How do you know when to raise your dram voltage or when to increase/decrease your cpu core voltage?
4. Is there anything else in the bios that I will have to fuddle with to get better performance when I OC? The DRAM performance area of the bios has literally like 30 options that could be changed. Do none of the other options not matter when it comes to overclocking?

I feel like there's probably a systematic way to do this but I don't know what that is. The "ultimate guide" seems to imply that you want to test one hardware part at a time. Is that really the case? If you figured out what the highest performance possible for each hardware piece (motherboard, memory, cpu) was, how would that help in the end?

I guess I just don't see a beginning to end path. As an example, now that you have my specs, if I asked one of you guys who knows a lot about a recommendation for my settings to OC, I'm sure someone would tell me where to set what as a recommendation. I would then like to ask, "how did you get those values?" so that next time I can reach the same solution myself.

I'd like to know how to figure that out myself. Sorry about the long post

Hi and WELCOM to the forum and congrats for gettin back to OCing
The simple best way basic...
Set a lower multiplyer on the CPU, perhaps a 7x... that allows you to up the HTT (CPU bus speed) which will then OC the RAM without the CPU hindering the RAM OCing. With the highest known safe voltage and working the timings you can find how fast it can run stable by testing with ncsa's quick method with memtest86. It takes time and effort as I'm sure you know Once you feel you have the top speed do a full test for max stability
The how to test w/memtest quickly is in the link...

Oh... on your #2 ? ... it is a deep subject... more info later from those that have the same memory as you
Then set a stiff divider on the RAM so the OCing will work the CPU with out the RAM hindering it.
Once you know the maxes of the two you can achieve a great OC.
