POLL What is your favorite motherboard brand?

Sabertooth is quite expensive. It is about $100 more than mid range motherboards. In my experience the mid ranges motherboards works decently well. I think the $100 could be better spent elsewhere unless you plan to use a cpu comsuming more than maybe 200w.

poor contact between VRM and heat sink

When the VRM on my motherboard gets hot, it starts throttling the CPU. I added a fan blowing to the heatsink on the VRM. It helped a little. But when I add more voltage to the CPU, it started throttling again. When I touched the heat sink, it is not even warm. I guess the heat sink was...

screw my Corsair HX750

I tried. The retailer couldnt find my receipt. But how come years ago when I sent back my HDDs(to Seagate and Toshiba) and video card(to Sapphire), they didnt ask for my receipt. I didnt register either.

screw my Corsair HX750

I found that the PSU cant sustain 750W anymore. When I pull 750W from the wall the PSU shuts off. So it can probably only provide 675W. Also is receipt commonly needed for RMA? I never keep receipts that long.

Fan splitter problem

I will provide more details of my experiment. Maybe the problem is the black and short cable. The purpose of that cable is to reduce the speed of both fans. When i unplug one fan, the other fan spins faster!

Fan splitter problem

I have more fans than the number of plugs available on my motherboard and I have been using Y splitters for a couple of my fans. I only recently realized that using Y splitter and have both fans plugged in actually decreases the rotation speed of both fans. That means if i plug both fans to...

Whats the point of a CPU liquid cooler that just sit on top of the CPU?

If memory access is an issue, they can have heatpipes extend to the left and have a tower like heat sink there, instead of the usual straight tower blocking memory access. Like how laptop cooler can make turns. Edit: Never mind, I didnt notice there are memory sticks on the left also.

Whats the point of a CPU liquid cooler that just sit on top of the CPU?

I stumble upon this weird CPU cooler. http://asetek.com/customers/workstations/hp/hp-z420-workstation.aspx To my knowledge, the whole point of using liquid cooler is to have a larger cooling surface area and dump heat outside by transfering heat using liquid. But this cooler just sit on...

What was wrong with your HX750s? The problem is if I were to RMA my PSU, I need to buy a PSU to use while it is gone. By the time my HX750 comes back I will have 1 extra PSU that I dont need.

My solution to this problem, buy a good speaker with SPDIF input and connect your headphone to the speaker. I prefer this way than buying a good sound card.

The PSU is about 4 years old. It has been running 24/7 almost everyday. It worked fine until I upgraded my rig. Before the upgrade my rig was pulling about 50% of its capacity. After the upgrade my rig used about 85% of its capacity. Everything is fine EXCEPT the PSU is making some high...

Best silent CLC / fan setup

Personaly I prefer single 120mm/140mm radiator over dual width for CPU. Single width radiator can be installed at the back of the case. Most people mount dual radiator on the top of the case. To push/pull air up requires much more work than to push/pull air horizontally. I found that fans...

question about scanf

"1, 2 " works, "1, 2 3" works too since scanf just ignores the rest after it found 2 matches. Your guess seems correct for the most part. That is, the quoted only actually applies to the text immediately preceding what that page describes as the "format specifier". That means the quote on...

question about scanf

I have been using C for a while, but I encountered this today and its behavior is different from what I expected. scanf("%d,%d",&d1,&d2); this matches "1,2" as expected but it also matches "1, 2", why? Since it matches "1, 2" I thought maybe its because scanf ignores whitespace before any non...

Buying new card, asking for opinions GTX 780 vs R9 290

I prefer MSI R9 290 personally. Its cheaper, quieter and cooler. If you are lucky it could be unlocked to 290X. I think you wont notice a difference between 3GB and 4GB unless you do mining.

video card overheat problem please help

I did consider all those cards. PCS+ and XFX DD have only 2 years warranty whereas the others have 3. MSI is $30 more expensive and TRI-X is $100 more. Im not sure if the extra is worth it. The gigabyte is at the same price.

The ambient is 22C. gpuz show vrm 1 temp 102C vrm 2 temp 71C. Thats with fan running @ 100% Yes I have considered this. Remember the last test I have done is with side panel off so airflow should not be an issue in that test. I will add fans for sure I am just waiting for parts.

Dont you think even with the variation taken into consideration, the difference is too great? The test done by VR-ZONE ran their card at only 1808rpm and peaked at 79C while the fan of mine ran at 3000+ and peaked 92C?
