New RAM - PC won't boot nor show screen

maxim_united · Oct 11, 2015

Hi experts,

I'm new here, so hello everyone.
I have:
- Intel's DH55TC motherboard
- 2x 2GB DDR3 Kingston PC3-10700 (667 MHz) P/N 99U5471-002.A00LF

Current working setup:
Channel A DIMM 1 - Empty
Channel A DIMM 0 - 2GB DDR3 Kingston PC3-10700
Channel B DIMM 1 - Empty
Channel B DIMM 0 - 2GB DDR3 Kingston PC3-10700

Recently, I've purchased (after some research):
2x 4GB DDR3 Hynix 1333MHz PC3-10600

Setups I've tried:
(1)
Channel A DIMM 1 - 4GB DDR3 Hynix 1333MHz PC3-10600
Channel A DIMM 0 - 2GB DDR3 Kingston PC3-10700
Channel B DIMM 1 - 4GB DDR3 Hynix 1333MHz PC3-10600
Channel B DIMM 0 - 2GB DDR3 Kingston PC3-10700

(2)
Channel A DIMM 1 - 4GB DDR3 Hynix 1333MHz PC3-10600
Channel A DIMM 0 - Empty
Channel B DIMM 1 - 4GB DDR3 Hynix 1333MHz PC3-10600
Channel B DIMM 0 - Empty

(3)
Channel A DIMM 1 - Empty
Channel A DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600
Channel B DIMM 1 - Empty
Channel B DIMM 0 - Empty

(4)
Channel A DIMM 1 - Empty
Channel A DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600
Channel B DIMM 1 - Empty
Channel B DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600

In all new configurations the PC doesn't boot nor connects the display (I've tried VGA and DVI).

What am I doing wrong? Is the new memory incompatible?

Thanks,
- Maxim

Look at your model number and see if it is on this page: http://www.intel.com/support/motherboards/desktop/dh55tc/sb/CS-030954.htm#tested. If not, then there's a strong chance it is not compatible. Bear in mind your RAM needs to be non-ECC and unbuffered. Also, I'd refer to your manual as some motherboards are very specific about which slots should be used in which order.
Before you do all that, take the RAM out and make sure you have FULLY seated it (clips at the end of slots click downwards).

My guess is that the new DRAM may be well 'new' - if recently manufactured it will prob be made with high density memory ICs (chips) which aren't compatible with most all the 1156 mobos. Would look for an older model of DRAM like GSkill's Ripjaws line (the original Ripjaws not the x or Z lines which also use high density ICs), or their NT series of value DRAM. Further, there are no guarantees when mixing sets so would get a single set of the full amount you want/need

Thanks for the answers.
I've been in the link you've sent as part of my research. And also here.
This is what I bought, as it was close as possible to that list :
http://www.ebay.com/itm/381314138712

I've definitely checked that they are seated properly.

Boot with the old RAM and update your BIOS. Reset the CMOS and try the new sticks again

maxim_united · Oct 13, 2015

syked3 :

We have progress.
Did as suggested. Updated BIOS and reset CMOS.
Tried this:
Channel A DIMM 1 - Empty
Channel A DIMM 0- 4GB DDR3 Hynix 1333MHz PC3-10600
Channel B DIMM 1 - Empty
Channel B DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600
Didn't boot.

Tried this:
Channel A DIMM 1 - Empty
Channel A DIMM 0 - Empty
Channel B DIMM 1 - Empty
Channel B DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600
Worked!

Suggestions what to try next?

syked3 · Oct 13, 2015

Try the 4GB Hynix in each slot (1 stick only) and see if it boots. I want to see if you have a bad RAM slot

maxim_united · Oct 13, 2015

syked3 :

Just tried this and it works too:
Channel A DIMM 1 - 2GB DDR3 Kingston PC3-10700
Channel A DIMM 0 - Empty
Channel B DIMM 1 - 2GB DDR3 Kingston PC3-10700
Channel B DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600

This proves that all of the slot are valid (since Channel A DIMM 0 worked in the original setup).
Could it be that I cannot use both Hynix-es ?

syked3 · Oct 13, 2015

The hynix sticks, did they come as one kit?
Put the all the sticks in, go to BIOS, enable XMP, increase the voltage on the memory controller and the DIMMs by +0.005V and see what happens

Tradesman1 :

Apologies OP. Tradesman1, what would you recommend he does now?

maxim_united · Oct 13, 2015

OK now I'm totally baffled.
This now works!
Channel A DIMM 1 - 2GB DDR3 Kingston PC3-10700
Channel A DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600
Channel B DIMM 1 - 2GB DDR3 Kingston PC3-10700
Channel B DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600

Just to recap:
All these didn't work:
(1)
Channel A DIMM 1 - 4GB DDR3 Hynix 1333MHz PC3-10600
Channel A DIMM 0 - 2GB DDR3 Kingston PC3-10700
Channel B DIMM 1 - 4GB DDR3 Hynix 1333MHz PC3-10600
Channel B DIMM 0 - 2GB DDR3 Kingston PC3-10700

(2)
Channel A DIMM 1 - 4GB DDR3 Hynix 1333MHz PC3-10600
Channel A DIMM 0 - Empty
Channel B DIMM 1 - 4GB DDR3 Hynix 1333MHz PC3-10600
Channel B DIMM 0 - Empty

(3)
Channel A DIMM 1 - Empty
Channel A DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600
Channel B DIMM 1 - Empty
Channel B DIMM 0 - Empty

(4)
Channel A DIMM 1 - Empty
Channel A DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600
Channel B DIMM 1 - Empty
Channel B DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600

(5) after BIOS update and CMOS reset
Channel A DIMM 1 - Empty
Channel A DIMM 0- 4GB DDR3 Hynix 1333MHz PC3-10600
Channel B DIMM 1 - Empty
Channel B DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600

All these do work:
(1)
Channel A DIMM 1 - Empty
Channel A DIMM 0 - Empty
Channel B DIMM 1 - Empty
Channel B DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600

(2)
Channel A DIMM 1 - 2GB DDR3 Kingston PC3-10700
Channel A DIMM 0 - Empty
Channel B DIMM 1 - 2GB DDR3 Kingston PC3-10700
Channel B DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600

(3)
Channel A DIMM 1 - 2GB DDR3 Kingston PC3-10700
Channel A DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600
Channel B DIMM 1 - 2GB DDR3 Kingston PC3-10700
Channel B DIMM 0 - 4GB DDR3 Hynix 1333MHz PC3-10600

Maybe the BIOS update and CMOS reset somehow did help?! However this doesnt explain why the 5th setup I tried failed. :/

syked3 · Oct 13, 2015

It may come down to mixing two different brands of DRAM which is causing your problem. However, if config 3 works then I'd stick with that. But for future reference, don't mix two different brands of DRAM. CMOS and BIOS update probably did help

maxim_united · Oct 13, 2015

Great! Thanks guys for the help! I was close to returning them.
Not mixing DRAM => Lesson learned

Tradesman1 · Oct 13, 2015

It's booting yes? IS the system seeing and able to use all the DRAM

maxim_united · Oct 13, 2015

Yes. Windows reports 12GB of usable RAM. Anything else I should test? (and how)

syked3 · Oct 13, 2015

That's good news. I'd recommend keeping it running in that configuration

Tradesman1 · Oct 13, 2015

Could just run and see if problems or maybe run something like ROG Real Bench to check for stability or the rig

maxim_united · Oct 13, 2015

Ran RealBench. No issue. Thanks again everyone!

Glad all is well
