Tried taking stuff out to see what's causing it, and it seems to be either the CPU (2500k) or mobo (GA-Z68X-UD3H-B3, I think). Its driving me bloody nuts, and only happens when I'm booted into something (is fine during BIOS), has anyone ever heard of this??
I had this problem too (twas driving me nuts) and what worked for me was lowering the CPU and case fans speeds using SpeedFan.
My BIOS has no option to disable the power features... C1 and C3 I think... but this supposedly works well for others. I also put my PC back onto the carpet floor, my thinking is that there might be less vibration than on a shelf... I've no idea

try dial back your OC if you have one. it could be the VRMs packing up.
Yeah I'll give this a go soon enough, currently clocking at 4.5GHz. Getting into the BIOS is a bit of a nuisance though, it displays for literally a second thanks to the gigabyte quickboot thingDeleted User wrote: »Try making a little cone like a megaphone to narrow down where its coming from. It helps to open the case up as much as possible to narrow down where its coming from.
It's definitely coming from around the CPU, not sure where exactly though, but it's under the heatsinkWhen does the whine happen? I had a PSU that would wine when the framerate in games would surpass 300fps (title screen of minecraft for example)
Try disabling power saver features in the bios and see if that helps.
er, it's more noticeable when under low load, like when the log in screen for windows is displaying, again, I'll look in the BIOS for that stuff..I had this problem too (twas driving me nuts) and what worked for me was lowering the CPU and case fans speeds using SpeedFan.

Definitely not the fans as I've been messing around and trying with each turned off. Going to try the power saver stuff now.0 -

Is there nothing to talk about these days? :P
Decided to start accumulating a few bits and pieces. Bought 16gb (8x2) Mushkin DDR3 1600MHZ PC3-12800 Blackline Frostbyte 1.6V CL9
Haven't seen many people use mushkin over here, can't beat a lifetime warranty tho!0 -

Calm before the storm with haswell, 8xxx and 7 series gpus coming out in the next 8-10 months
Ive been spending my time looking to replace my G500 mouse with a Zowie EC1
how much did your RAM set you back.
Its not really used due to G.skill and corsair being cheaper usually and they all use the same Elpida ram.0 -

http://www.anandtech.com/bench/Product/518?vs=660 Actually according to benchmarks its alot better the the gtx 570 in most games.
http://www.anandtech.com/bench/Product/548?vs=660 and based on most games there pretty similiar but look at those bf3 benchmarks blows it out of the water! Not to mention poor catalyst drivers and my love for nvidia
Not really. Cat 12.11 boosted BF3 performance quite a bit.

Nice post but im guessing the benchmarks from anadtech wouldve been launch drivers for the two cards so know im really confused. Im still going to go with gtx 660 since its only one 6 pin pwc for future sli maybe0 -

Is it purely a question of speed or is there some other factor that governs what sort of connection monitors require?
A big concern for things like monitors would be the latency/overhead and signal quality/loss. I'm not much of a guru so I don't know if USB would be a suitable interface but there is other things to consider than the transfer rate.
I guess I could google this and give a better answer but I'm lazy

well im not much of a reviewer and im not sure if this belongs in the HW discussion thread..
setup:
Akasa FC6 6 channel fan controller. (30W per channel, 0v->12v)
Asrock z77 extreme6
8gb ram
pentium G2120
corsair A70 heatsink (passive!)
AX750 (fan off)
HD6450 passive
the SP120 Quiet Editions (SPQE) comes in a very nice package, looks fantastic with the interchangeable colour rings, a resistor cable to slow them down more (which i left off for the testing) etc etc, but you all already know that. the Gentle typhoons (GT) looks bland, grey, industrial and well to be blunt just plain ugly.:o
the nitty gritty is that the SPQE runs at 1450rpm, and the GT model i have are the 1850rpm's. i cant really compare rpm vs rpm without a lot of hassle going through speedfan via the mobo, so i just did % of total power from 0v to 12v.
i also dont have a tachometer so i used my face as a judge, and put them right against my ear for sound
@~10% (~1.2v) , they both sound the same. its hard to tell which is pushing more air cause theyre both pushing very little.
@~20%, a noticeable click, though soft, can be heard from the SP's. this is common with cheaper fans when they're under powered on a fan controller. GT takes the edge on air, slightly. rpm advantage i figure. no clicks from GT even at 5%.
@~40% clicking more apparent on SP. soft "whirr" from the GT and SP. GT definitely push more air.
@60%, clicking dies, but is replaced with a noticeable "clunking" sound every few revolutions on the SP. to make sure its not a faulty fan i tried my second SP with the same result, what that means i dont know. both faulty, or both normal. GT noise almost indistinguishable from 40%.
@80% clunking still there, but less apparent as air noise "whirring" is getting fairly loud. GT pushing much more air, and much more directed. its an unfair comparison cause the AF (as opposed to SP) series fan is meant to be a the a rad fan iirc so would be better with the whole static pressure thing.
EDIT: AF is high air flow and low pressure, SP is high pressure. bit disappointed in SP's now. i thought i was doing an unfair comparison cause i thought the AF was actually the high pressure ones, thinking i was comparing GT vs SP as apple vs oranges w/r/t static pressure.
@100%, the GT hasn't actually gotten much louder than around 60-70%. bit of a squeal off the SP's, and clunking has died. id guestimate that the GT's are pushing ~50% more air at this point. rpm advantage for sure. GT's quieter than SP at this point though.
overall, its an easy victory for the GT's.
they were quieter and pushed more air at every level.
I have to stress that moving my ear away from the SP's even 50cm's and the squeal is almost inaudible. im doing a very unrealistic test with no real dBA meter or tachometer.
results will vary person to person guaranteed.
ive become very sensitive to noise as of late for some reason, but to complicate it further, "loudness" is measured in a logarithmic scale, meaning your ear perceives a change in 3db as a doubling in loudness.
its an interesting conclusion because corsair claims 23 dBA and skythe says the 1850s are 28 dBA.
ive had the HTPC running the SP's for a few days now, and none of the housemates have commented on noise, so id say the average person will not notice any difference. for that reason, id have no problem recommending the SP's to people, and will advise them over the GT's for the aesthetics alone, and theyre around E2 cheaper.
for myself though on my personal rig, and anyone using water cooling, the GT's push much more air at the same noise level. in particular, the SP's dont like low voltages nearly as well as GT's. (though theyre much better than standard coolermaster fans at handling it)
any questions/suggestions etc welcome.0 -
