    Reduced screen brightness with clean install (XPS 12)

    After a clean install of Windows 8 on my XPS 12 my display brightness is lower than it was before. The brightness slider still functions fully, but every brightness stage is dimmer than it was previously. I have installed the latest available Intel HD Graphics drivers from Dell and updated the...

    R9 290X memory clock causing lag in flash video playback

    So my PC has randomly started lagging when playing back some flash videos in my web browser. Bizarrely it happens with twitch VODs, and some YouTube videos, but not live twitch or other YouTube videos. The issue seems to be that the memory clock randomly downclocks to 150MHz for no apparent...

    Windows cannot detect graphics adapters of any kind

    So I was happily using my R9 290X up until today when I reapplied the patches and CRU tweaks to allow my Korean monitor to use 120Hz, as I have done on several occasions after updating drivers. In my impatience I used a utility to restart my graphics driver (linked on the custom resolution...

    R9 290X Idle Core Clock At 100%

    For some reason my R9 290X has recently started to idle at 1030MHz core clock (maximum value at stock clocks), or around 1050MHz when overclocked to 1125MHz. The memory is successfully downclocking to 150MHz and ramping up to 1250MHz when needed, but the core remains entirely unchanged after...

    i5 4670k downclocking randomly

    So my i5 4670k that I got last week has started exhibiting some weird behaviour, causing me a ton of lag. It's downclocking to around 800Mhz frequently, which causes lag doing almost anything. Moving windows around, even scrolling can end up lagging while the chip does it. In game it clocks...

    R9 290X dynamic clock speed shenanigans

    So I've noticed that in the past few days my R9 290X has been behaving weirdly. Core clock seems to sit at 1030MHz 100% of the time, except when I'm overclocked, where it idles at about 1050MHz and jumps up to 1125MHz at load. Memory clock is similarly strange. 90% of the time it's at...

    ASRock Z87E ITX hard drive detection

    So I just put together my new mITX build using an ASRock Z87E ITX mobo. Everything is going great, except I can't seem to detect my two secondary hard drives (carried over from my last build) in windows. I'm using an mSATA SSD as my boot drive, and that works perfectly. However my secondary...

    i5 2500k won't overclock properly

    Background: I've had an i5 2500k for the last 18 months. It's never overclocked particularly well (never been able to break 4.4ghz, even at 1.35-1.4V VCore) but it's been working fine at 4.4ghz for around a year. Today I moved my computer into a new case (Fractal Design Arc Midi) and all of a...

    Overclocks don't stick on Windows 8?

    I just installed windows 8 this morning and re-applied my overclock settings. The BIOS clearly shows my 2500k is at 4.4ghz in the MIT window, but when I boot into Win8 both CPU-Z and Openhardware monitor show the frequency switching between a range of values from 1.6-3.7 ghz. The frequency...

    PC failing to boot after failed sleep

    I was attempting to install Windows 8 from the desktop installer, which was producing an error telling me to rename my C:\Users folder. Actually renaming the folder had no effect on the installer, so I figured that maybe because I used regedit to set the default from C:\ to F:\ it was causing...

    BSOD with any kind of OC (i5 2500k)

    I had a post a couple of days ago about not being able to get my 2500k to OC past 4ghz. Now the situation has changed, with any attempt to OC resulting in a BSOD (this is with the latest BIOS, everything on auto or with the CPU VCore set to 1.3V). The strange thing is that the latest BSOD was a...

    i5 2500k 4ghz OC limit?

    I followed this Bit-Tech guide: http://www.bit-tech.net/hardware/cpus/2011/01/07/how-to-overclock-the-intel-core-i5-2500k/4 for my Gigabyte Z68X-UD3P motherboard. It works fine at 4.0ghz but at 4.5ghz my PC fails to get past the windows 7 boot animation, and raising the CPU VCore to 1.36V didn't...

    5870 + slow FPS in source engine

    My 5870 is getting strangely low fps in CS: Source and Portal 2. Benchmarks show I should be getting well over 100 fps, but when I ran the source benchmark I averaged 55.7 fps. This wouldn't be too much of a problem, but I regularly see my FPS drop below 30, causing noticeable slowdown. My card...

    £50 Gaming Case

    I've reached the limitations of my Xigmatek Asgard (hyper 212 has 1mm clearance from side of case and 5870 brushes HDD) and was wondering what the best case upgrade for £50 would be. My priorities are size (space to go crossfire and hadve 2 or 3 HDD/SDD) and cooling (I want to overclock my 965...

    AMD Phenom II X4 965 Overheating?

    Last week I bought a new barebones PC system from Novatech. Everything worked fine, but running Battlefield Bad Company 2 my CPU fan started running extremely loudly. I have been considering a new CPU cooler but was willing to live with the noise in the meantime, however today I suffered 2...

    Low FPS from ATI Radeon HD 5770

    I just upgraded from an 8800GT to a XFX 5770 1GB, but am experiencing similar performance on my new card as on the old one (20-25 FPS in Crysis on high, 20 FPS on World in Conflict benchmark on very high and similarly low frame rates on dirt 2 and far cry 2). The card runs the desktop and older...
