It may not seem like much, but consider that we also had the memory at a scorching 1800MHz (7.2GHz Effective) and these were game stable settings. For a single 3DMark Vantage run we could do 1,290MHz but that was hardly stable and the increase in vGPU required for that was not worth it in the end. Great for those overclocking sessions and this is what this card is essentially built for. Try as we might we couldn’t find anything to fault about the Lightning. We are aware that despite the binned GPUs that are used for the Lightning range, further binning may be required by overclockers as we’ve heard stories of some cards being unstable at anything lower than -20’C.Those are far and few in-between and we’d think that the odds of coming across a sample like that with the reference cards is significantly higher than it is for the Lightning. So we’d not be deterred too much about such reports. During our testing we noticed something peculiar though and that is our GPUReactor module didn’t help at all. Be it installed or not the maximum clock speeds were identical. This doesn’t’ mean it’s not a worthwhile attachment as we’ve seen some other samples show gains with it installed. We aren’t entirely sure what was happening with our sample or if the limitation was somewhere else, but once again, at worst it can’t hurt your overclocks so you may as well use it. MSI once again has managed to make its graphics card stand out from the countless number of Radeon 7970s on the market. Most customised 7970s are special by virtue of a factory overclock and a cooler; however MSI’s card is different from purpose right through to execution. There’s no need to buy a card in the hopes that the mods for it are online as you essentially don’t’ need any and if you do they are simple enough to follow that virtually any competent overclocker can perform them. 40.871 There isn’t anything to dislike about the R7970 Lightning. It’s in every way what we hoped it would be and more. If you’re in the market for a purpose built overclocking graphics card with minimum fuss, this is the one to buy. [ The Overclocker ] Summary MSI has yet produced another worthwhile graphics card for the Lightning family. It’s simply the best Radeon 7970 money can buy right now. If you’re serious about overclocking and wringing out the best from the Radeon 7970 look no further than the R7970 Lightning. Would you buy it? Most definitely, this is the 7970 to own over and above all others. The Score 9/10 Issue 20 | 2012 The OverClocker 17
