Two days later, UPS picks up the Alpha, a week later the mainboard is replaced, free of charge, no questions asked and on its way back to me. Now THAT is much better than I ever expected!

Also got an almost full refund from eBay, the refunded everything but the shipping, so now I have an Alpha (i3, 8 GB, 1 TB) for 21 Euro. Good deal! smile.gif
I'm surprise that ebay doesn't require you to ship it back.

That's up to the seller, he probably knew he messed up (sold it to me defective on purpose) and didn't insist on me sending it back.

So I want to get a bigger CPU i7, and a larger power brick would this help with eliminating throttling? Im not worried about heat as if this is possible I will be strapping a h100i to its back

What 1150 cpu would you recommend for doing quite heavy work (video and photo editing, as well as development)? The gaming performance with my current i3 is good enough for me. I'm just curious as to what performance boosts I would get out of upgrading the cpu.

PS I am already dual booting linux mint 17.3 and windows 10. Would the performance boosts be evident in linux as well?

Thanks!

IMO the trick is to scout ebay on a regular basis for a T chip with higher base clock than the i3. Prices are all over the map; I actually found out I overpaid for my 4770t by quite a bit and from the same seller of the cheaper auctions nonetheless. Look for chips from system pulls. Since these are all OEM chips anyways having some sort of warranty is pretty much nonexistent I think. Amazon resellers and online retailers fluff their prices big time probably because there's not much competition or demand for the T chips.

Hello New to pc gaming also own xbox one and ps4
The alpha I have is a i7,1tb,8gb
Is it worth upgrading to a 250ssd and 16gb ram? And if so are they plug n play?

I did also remove the heatsinks cleaned and applied a nice amount of AS5 thermal grease, so it's possible that may have helped.

Last night I also started to go thru the main motherboard bios, looking for the fan control settings. Dell has this set to 92c before fans ramp up, I would much prefer it be set to 72c or 82c for the ramp up to allow for the gpu boost to not handicap.

If I can figure out the he and offset I will let everyone know. With the fans on a louder but performance setting it could make a huge difference with this little box.

I may also physically modify the pwm fan wiring to bypass speed control so they default ho max rpm. I again don't want to make this little system impractical, it's supposed to be small and quiet in a living room.

Another option may be to get a good bit of testing done on the smbios settings, the cpu fan ID is 0x27. Manual entry into a sensor control software may also be possible. (Hwinfo64 worked on both my Dell Precision M6600)

Have a great rest of the weekend guys. I will post stuff as I learn more.

I also ordered one of the large PA style 200 watt adapters normally used with the high end laptops from Dell, when it comes in I will retest everything under its hopefully increased power delivery headroom. There are voltage & current sensors active in the SMBIOS, so I hope they can actually deliver the needed watts to a new CPU, and this little integrated GPU.

Did you notice the TDP was set to 37.5 watts in the vBios? I bumped mine to 45 watts to try to keep it from hitting the power wall at one point, but then I got nervous about damaging the power system. I'd be curious if the bigger power supply would allow you to bump the GPU TDP to 50 watts and give you the much needed headroom for overclocking.

I also have been trying to figure out a way to edit fan control. The high temps are killing power headroom. I attempted to modify the motherboard bios, but couldn't find a way to kick the fans up earlier. I'm considering moving to a water cooler.

Hi

With the current discussion on modifying the Alpha case for cooling, is it plausible to take the components out of an Alpha and put them into another case?

This could possibly then help with cooling, etc.

Totally aware that one of the best things about the Alpha is the form factor and size, but wondered whether this is do-able?

Cheers

I thought about this briefly. The only real issue would be getting the I/O to line up as well as the motherboard mounting screws. I'm not sure if the mounting is standard mini itx

Before it has a score of 271 on 4130t. I upgraded it to 4670t (cost me $120 on ebay) and the score is now 440.

Nice. I too upgraded from the stock i3 to an i5. I went from the 4130T to the 4690T. I ended up paying $195 though... You got a good deal. The 4690T is a Quad Core, 2.5GHZ Base, 3.5GHZ Boost, 45W TDP. I seen a nice bump in my benchmarks and also in real world usage.

My Cinebench score was 485, not much higher than yours. Here were my results.

i3 4130T

Geekbench 3 Benchmark:
Single Core = 2801
Multi Core = 5928

Cinebench R15 Benchmark:
CPU (Single Core) = 115CB
CPU (Multi) = 290CB

Unigine Heaven Benchmark:
Quality: High / Resolution: 1920x1080 (All other settings: disabled)
GPU Overclock: +135 / +250
Score: 1172
FPS: 43.1 / Min: 8.1 / Max: 83.9

i5 4690T

Geekbench 3 Benchmark:
Single Core = 3288
Multi Core = 9927

Cinebench R15 Benchmark:
CPU (Single Core) = 154CB
CPU (Multi Core) = 485CB

Unigine Heaven Benchmark:
Quality: High / Resolution: 1920x1080 (All other settings: disabled)
GPU Overclock: +135 / +250
Score: 1358
