    The reason for what you are seeing has noted by Jacobsson and Noric as being dueo to your 32nm SB CPU being 45W TDP throttled to x29 @93 degrees. Only way I could see you hitting x32 would be (1) to improve cooling significantly to drop temps which would allow (2) installation of a 55W TDP i7-2920XM with an extra 10W TDP headroom to allow x32 mode. Though doing both is more costly and complex then simply offloading the 6460b and instead getting a IVB 6470b/8470p with a more power efficient x32 4C capable 22nm i7-3630QM, i7-3720QM or i7-3740QM. My very efficient i7-3740QM can do x34 4C mode. If I improve cooling further then I can get a full Throttlestop 1024M x35 4C mode bench run.

    It looks like NVidia is progressing well with their new 750Ti (Maxwell) significantly increasing energy efficiency so that it now pulls just 60W and is ~6 inch long (see here for the Anandtech review). That means that you could put one in the little Sonnet Echo Express SE II (still expensive) but should run from the internal PSU and still put out almost 40-50FPS in BioShock Infinite at 1080p Ultra Quality. All the pieces are coming together ... if only Intel would play nicely.

    Thanks for replying! Unfortunately not the results we were hoping for sandy bridge laptops... :( I don't think you'll be able to go past x29, because even if you lowered the temps, you are already hitting the 45W tdp wall. However, you may want to increase thermal dissipation so that you can run x29 in a more fresh environment. 93° is quite high.

    According to our findings, a cooler CPU environment (no bottom cover/better heatsink etc) prevent this kind of throttling. For example my 3820QM could only handle x34 for a couple of seconds, then x33 for a minute, then settles @x32.5. I made some cooling improvements and now I run x34 for a full run of TS 1024M w/o problems.If you can lower your temps you will be able to hold x29 for much longer, but I don't believe you will go past x29 since you CPU never indicated to do this even for a short while.Also, I guess you are using a 90W ac-adapter?EDIT: You can clearly see that your CPU throttles @~93c, which also seems to be the limit for our 37XXQM/38XXQM. The Goal is simply to stay below ~93c.

    CROSSFIRE IS WORKING ON WINDOWS! What a night. my first psu (old 400W) has blown/burned in the past weak and I replaced it with a 730W one, and this last one when I was just a hour ago while I was testing my new 290x with the laptop. Since I planned on buying a second PSU to replace the 400W that has just blown, I've said I'll put the two 6950 in the desktop PC with this new PSU I bought two days ago to replace the first and I said I'll try mining a little. Booted windows and so the second GPU can't be used to mine as its locked to low clocks and shows disabled in catalyst. Found some thread with the same problem and they said it's because I don't have dummy plug on one of the cards and op saying catalyst 13.4 legacy works anyways (without the dummy plug). I've installed it and it asked me about crossfire! I answered yes/next and it said a crossfire bridge isn't connected, connected it and voilla! crossfire! TL ,DR: crossfire HD6950 on two 1x links works on catalyst 13.4 legacy (64bit) AMD Radeon HD 6950 video card benchmark result - AMD Phenom II X4 20,Gigabyte Technology Co., Ltd. GA-MA770T-UD3P Now there is something to compare to, for example to see what have changed in catalyst code to see if it can be enabled! BF4 dx11 ultra, test range: two x1 PCI-E 2.0 HD6950 crossfire disabled: 24fps two x1 PCI-E 2.0 HD6950 crossfire enabled: 37fps one x1 PCI-E 2.0 290x: 90fps BF3 ultra, empty caspian border server, (this one seems to be much more affected by pci bandwidth, for example with x1.2 290x I get 45-70fps where it should be much higher): two x1 PCI-E 2.0 HD6950 crossfire disabled: 25-27fps two x1 PCI-E 2.0 HD6950 crossfire enabled: 45-60fps feels there is some microshuttering (I'm not sure, never had crossfire, 45 feels like 30-40, I think) one x1 PCI-E 2.0 290x: 45-70fps (lots of trees, or particle effects, like in caspian border makes it drop to 45, felt a bit smoother than 45 with crossfire) Crysis 3 high textures, high detail, welcome to the jungle mission, jungle entrance (staircase): (People say its PCI bandwidth limited, haven't confirmed it myself yet) two x1 PCI-E 2.0 HD6950 crossfire disabled: 13-14fps two x1 PCI-E 2.0 HD6950 crossfire enabled: 25-26fps one x1 PCI-E 2.0 290x: N/A, Didn't test yet Keep in mind this(not the 290x) is a legacy driver (which is even for 5000 or older series) but scaling is definitely there!
