Brian1965,
Good to read of progress. On Passmark your z620 has the 2nd highest system rating- very well done and and you're not done!
Perserverance with the BIOS has paid off. I was lucky as all of my HP z's arrived with UEFI already.
By the way, in the last couple of posts, I'm only seeing pale yellow triangles for the images. EDIT: After posting the reply, the images are working again.
I notice on Passmark that the 3D rating is given as 0.0. The 3D @ 10341 is at GTX Titan Black level- that must be with the M2090 (?). And, if so, I'm having one myself. I would expect a K4200 on it's own to be in the 4500-4800 range. The first go with my z620 also returned a 0.0 3D and Passmark said it the result of the 3D graphics tests missing one test for some reason. This happend before on the Precison T5400 when the test could not reze a Direct X window. If you go to Passmark "Bottom 100", almsot all the listings are system with a 0.0 3D while they have may very good marks for the others. It's odd the way that is set up, but Passmark says it's due to tthe number of headless systems running without a GPU..
Also good to read that the M2090 cooling can get sorted. It appears the new waterblock has a uses a pair of screw-in fittings for hose /pipe attachment. Perhaps the kit has those or ou can buy one with a plain protruding tube and the Corsair tubes can be cut, slid over, and clamped- clamped twice. Check the diameter of the Corsair tubes so the flanged tube on the fitting is appropriate. My worry is not to have a really positive attachment as the cooling fluid is under pressure and accidents have happened,.. This might be a job for car screw-down hose clamps as used in the Morris Minor era for the heater hoses. Perhaps ask the firm that made the water block the best way and they may well have the hardware. I'm not sure, but there must be a procedure for bleeding the air from from the fluid loop. As the H90 is sold as a closed system that in theory never needs that (?), it may be somthing to look into.
On the subject of mounting the pump / fan / radiator, these are getting better but typically are a bit noisy- pulses a bit like a high-volume acquarium pump, but the fans are quiet. If it is exterior-mounted, you might make an enclosure with the unit inset - the fan unit not on the front surface and so the enclosure can sit under the desk so you have the desktop as addiitonal sound insulation. I'm thinking of the extra fuss apropos of using your system for music editing, but perhaps you do that with headphones.
In my news, the z620 goes from bad to worse. As I had updated the BIOS to 3.88 earlier and all the flashing screens appeared, I tried to restore it to the earlier, version, and tried updating again, but it's gone bonkers- alternately can not find the system disk, and then tries unsuccesfully in a CMD to connect to some "FXE" network. Perhaps it's a virus. there is a BIOS recovery procedure but I may to clear CMOS and start all over - which I've never had to do in 20 years. This is bad timing for me as I need to concentrate on the Big Building. Disappointing as I don't like to have unresolved problems and I'll need this system for all the large renderings pending, possibly 50-60.
So, yes, let me know what happens. The Tesla seems to have real potential.
Cheers,
