Mid-range PC - mid-life upgrade

(I figured I’d take this back here rather than cluttering the specs thread)

Yeah - I’ll do the OC first and then see how I go from there re memory.

I also need to put the GPU through its paces via some stress testing in the next little while, to make sure it is all good given the limited time warranty. Temps seems to be around 75C under load, which certainly doesn’t seem low, but appear to be within expected.

Apparently there’s some fan curves one can adjust to help with temps if they are high…I don’t much mind about power consumption if it helps with temps and the water cooling fans are louder than the GPU fans anyway. That’s what the noise cancelling headphones are for! :wink:

I’ll post some charts and graphs for my oc, fan curve etc. tomorrow night. Have to hit the sack.

Well, I’ve OC’d the i5 4690K to 4400MHz and that seems to be working okay so far - 1.20V voltage and on a hot summer’s day with a light mission in DCS the CPU runs at about 50C. The stress tests get it higher but actual use (DCS) seems fine.

The standard CPU Prime95 cycle is about 71C but the max heat cycle stress tests gets the CPU temperature up into the high 80’s, unhealthily high…but then, that’s a very extreme scenario.

I might be able to OC up to 4500MHz or alternatively leave the clock speed at 4400MHz and reduce the voltage a bit to lower the temps as everything seems very stable - in any case, I’m pretty happy with the initial results, given this is the first time I’ve tried overclocking.

I’ll need to run some heavier missions in DCS and try out X-Plane etc. also to see how the temperatures react.

I’ve been hesitating buying more RAM as my current 16GB is at 1600 clock speed i.e. relatively slow - but then upgrading the motherboard and buying all new RAM is quite a major upgrade, so I might see if I get another 16GB at the current clock speed and see how it fares - cheaper and might keep me in the game for another year.
