I recently bought a PC from a fairly well known online supplier. i5 3570k @ 4.2ghz, 8GB 1866mhz RAM, 7950 3gb along with all the usual. It's faultless and I'm happy with it bar one thing. It came with a VTX3D graphics card (I didn't get to pick the brand) and through using afterburner have come to the conclusion that the vram is of a lesser quality than it should be. By this I mean for it to run 100% stable in a demanding game (crysis 3 and bf3 for example) I actually have to run the memory clock at 1230mhz from the default 1250mhz. Whilst it benches in things like 3dmark 11 at 1300mhz (max), to be perfectly stable in games it needs this slight under clock. If I don't run it at 1230mhz I get either a full grey, brown or purple screen with lines running on it and system crash. The core happily runs at 1020mhz from the default 800mhz with just the power slider at +20%, default voltage being 1.093v.
Although the vram is under clocked slightly, obviously games still run well and as they should, 3dmark 11 posts P9158 for instance. I'm also satisfied with the none reference cooler. Would you accept a card like this or will the vram crap out more so in the next 6 months meaning before long I'll be running it at 1200mhz? I used to have an ASUS 6770 1gb and that had memory under clocked by default, 1000mhz from 1200mhz if I remember. Could VTX3d be using lesser chips and clocking them already upwards to 1250mhz to make stock? Not sure if to try and return only to have it replaced by another VTX3d card that could actually be worse or the possibility of being sent a reference cooler 7950 card?
Note: The drivers are 13.1, everything appears installed as it should be (this being the only issue) and the cooling in my case is good with a side fan over the card itself. The PSU is a branded 750W Bronze rated supply. My card never goes above 65c, it's usually 61-63c - fan profile has been adjusted.
