Questions about upgrading - Page 3

post #21 of 36
Now the above was written for a user with bad cooling on the CPU and motherboard, so your overclock will differ slightly.

You want to aim for the highest your CPU, NB and RAM will go, since you have better quality parts and thus a greater chance of a higher stable overclock. You can aim to run your HT-Link (FSB) as high as you can (240-300?? Some users get higher, I find that anywhere between 200 and 250 usually gives you enough variable options to max out your RAM and NB too) that gives you the best combination of CPU multi, NB multi and RAM multi.

You need to follow each step to find the limits of your CPU, NB and RAM, then find the best compromise that allows for a focus on the highest NB overclock. Given you have an unlocked CPU multi, the NB will be your defining factor. Once you've worked out the best and most stable CPU/NB overclock, get your RAM to the best possible mhz speed and set those timings as low as they can go.

You might now be thinking to yourself that overclocking with multipliers is easier than all of this above, so why not just do that? Well I've consistently found that higher, more stable overclocks come with LESS voltage increase (thus less heat and damage) when the overclock is done right using the FSB and multi's to refine.

It WILL take longer, but it's absolutely worth it.

Let me know if you need more help.

Also this guide is great, you should read over it all before starting though my guide will just get you from A - B without knowing the background:

Brilliant, thanks for all the help

I'll read through everything fully and have a go at overclocking my system tomorrow.

I'll check back with the results

You are welcome, and I've left this window open in my browser, so I'll keep it open till you repost.

I should add one more thing as a note for you that will differ from the overclock guide above I wrote for the other poster:

When overclocking higher, you will inevitably need to increase your NB (separate from CPU-NB) volts in your bios. Up by .1v is usually fine, but it is something you should expect as you increase CPU and NB speeds. It's possible to hit a certain point (so I've heard, perhaps experienced) where your CPU won't stabilize any higher regardless of volts, because of the voltage in your CPU-NB or NB section, even if they're running at stock.

The further into overclocking you get, the more your notice the finer points, like how a NB overclock affects your CPU overclock. Both are components of your CPU, both share temp increases together from either's volt increases and they have a shared relative performance window, where your NB being higher or lower MAY help stabilize a CPU overclock, or vice verca.

I say this because given you are probably going to aim for a 4ghz OC, you should probably allow for a safe and small NB overclock as you shoot for 4ghz on your CPU - something around 2400-2600mhz on 1.35volts CPU-NB and +.1v NB should be all you need to continue up towards 4ghz giving you the headroom and an idea of your likely temps @ 4ghz.

It's all inter-related, you'll find out as you go. Just keep temps in check, parameters within respectable ranges and keep your NB/RAM conservative whilst going for CPU, or CPU/NB conservative whilst going for your RAM, or CPU/RAM conservative whilst going for your NB. All of this should be done with a mindset of establishing a little headroom for the final collaboration.

At the very end you mix them and balance out your final overclock - this is where I'm at now, and it's the most fun part

Enjoy, and we'll be here with you along the way. Peace

Those are pretty much the most un-optimized games out there that you're trying to run...

Play Bad Company 2 or Starcraft II which are nicely optimized for Quad's and you'll be perfectly set.

I'd heard Assassin's Creed, GTAIV and Splinter Cell were shoddy ports. I just didn't realise how shoddy!

I'm not holding out hope for ACIII PC!

http://www.techspot.com/review/305-s...ce/page13.html

Starcraft 2 only REALLY makes the most of 2 cores, though it will spread the workload out over more if given the option.

Regardless, a bad Windows 7 install or driver-clash was the real culprit of the initial low scores and now the OP has fixed that with a fresh install and is now overclocking to maximize his already corrected scores.

The previously listed games are relatively unoptimized, but that doesn't change the number of frames per second his Rig should be seeing compared with the initially woeful numbers he was posting, as the expected fps are only relative to other users of the same unoptimized game on their respective hardware. Basically, the fact that the games are unoptimized is completely irrelevant to this thread ...

Thus I'm not actually sure what you are trying to tell the OP here at all, nor that you were sure either ...

Got it stable @ 3.8GHz @ 1.4v

The temps didn't budge any higher than 52°C for 60mins.



Gonna continue on to the magical 4GHz (if I can).

Badass dude - congrats!

Where is your NB at?

How about your RAM? Which 8gb kit is it (newegg link pls)?

Did you notice a jump in speed with your CPU overclock?

As far as temps, were you looking @ individual core temps or the TMPIN number? They seem a just the tiniest little bit high for individual core temps - how sure are you of your cooler's seating and thermal paste application? Are you running push/pull fans?

oh boy that board of yours is 4+1 phase power , unless u got some mosfets installed on it its very dangerous to OC need at least 8+1 or 8+2

I was monitoring the individual core temps with Hardware Monitor.

The thermal paste was already on the cooler. I'm using the stock fan (pull) that came with the H50.

Uh-oh!! Looks like a new mobo

I'll leave overclocking for now, lol
