HPE h8-1287c GPU Upgrade

Recommended Posts

Posted · Original PosterOP

I have an HP hpe h8-1287c that I have made upgrades too. I installed a boot ssd, already transferred windows 7 sp1 64bit onto it. I took out the OEM ram and installed 4x4gb 1600mhz hyperx ram. I installed a new evga 450w bronze 80+ (bt) psu.

 

Before I bought the psu I tried to install a 1050ti mini because the OEM psu didnt have a GPU cable. But the mobo gave some beep codes that I couldn't find a guide online for. That's when I bought a rx 470 and the psu.

Now my problem is the PC boots but as soon as windows loads the fans on the GPU stop spinning and it's not detected anywhere in windows. I ended up having to update the bios straight from HP's website to try to fix the problem but it didn't help.

 

An AMD HD 7870 2gb does work in the build, and the rx 470 is tested in my main rig.

 

Cpu: i7 3770 with cryorig c7 cooler

Gpu: xfx rx 470 4gb

Mobo: ipmmb-FM (formosa) with bios version 8.21 rev.a

Psu: evga 450 bt

motherboards of prebuilt systems don't necessarily (and usually don't) follow PCIe 75w rule, quite often they are only good for 25w. That's probably why neither of the newer cards worked. As for the 7870, maybe it's just not pulling much power from the PCIe slot.


Studying abroad, ditched the crappy laptop for a do-all laptop double. Dried factory CPU paste, long memory timings, cooler cools the inductors but not the mosfets and an inch of unused internal space on both left and right

Model: HP Omen 17 17-an110ca CPU: i7-8750H (0.125V core & cache, 50mV system agent undervolt) GPU: GTX 1060 6GB Mobile (1696MHz 0.812V ~ 1860MHz 0.95V) RAM: 12GB DDR4-2666 19-19-19-43 2T Storage: 128GB Toshiba NVMe SSD (KBG30ZMV128G) + 1TB Seagate 7200RPM 2.5" HDD (ST1000LM049-2GH172) Monitor: 1080p 120Hz IPS G-sync

 

The best thing to do is reading the clock speed that doesnt end in a pair of zeros. Software voltage readings are wrong if your motherboard's not a high end model

CPU: i7-2600K 4493MHz (multiplier: 43x) 1.35V (software) --> 1.4V at the back of the socket Motherboard: Asrock Z77 Extreme4 (BCLK: 104.5MHz) CPU Cooler: Noctua NH-D15 RAM: Adata XPG 2x8GB DDR3 (XMP: 10-11-11-30 2T 2133MHz, custom: 10-11-10-30 1T 2229MHz) GPU: Asus GTX 1070 Dual SSD: Samsung 840 Pro 256GB (main boot drive), Transcend SSD370 128GB PSU: Seasonic X-660 80+ Gold Case: Antec P110 Silent, 5 intakes 1 exhaust Monitor: AOC G2460PF 1080p 144Hz (OC'd 150Hz) TN Keyboard: Logitech G610 Orion (Cherry MX Blue) with SteelSeries Apex M260 keycaps Mouse: BenQ Zowie FK1

 

Results: Cinebench R15 Single thread:159 Multi-thread: 770 (thx Meltdown Spectre patch) Super Pi (v1.5 from Techpowerup, PI value output) 16K: 0.11s 1M: 8.4s 32M: 7m 45.9s

Wow I hope I don't have to change the mobo. Ivy bridge mobos are expensive.

It randomly started detecting the 470, and it tests fine in games. idek
