Proliant Server Not Booting, Suspected RAM Issue

[SmokieyGrub]

Hello, first I would to state that I am experienced with desktop computers, but am very new to servers.

I recently purchased a Proliant ML350P G8 server. I wanted to convert it for hosting multiple games and web hosting. I switched the CPUs over to a pair of E5-2695 V2. I then wanted to switch the ram from 16Gb to the max because DDR3 is cheap(ish).
I bought 24 sticks of 16GB 2Rx4 PC3L-10600R. 

With one CPU in, it will run with 12x16GB, but when both CPUs are in, it refuses to boot. It will get past the initial boot sequence(the one that looks like command prompt) and then immediately loop back after it got to the HP-looking boot window. The weird thing is, both CPUs work on their own, and when there are 2 CPUs and 1x16GB per CPU. It also runs with both CPUs when in each channel there is 1x16GB 2Rx4 PC3L-10600R and 1x8GB 1Rx4 PC3-12800R.

I see no reason why it shouldn't be able to run with 3x16GB 2Rx4 PC3L-10600R in every channel, yet it doesn't work. I am considering trying to get 16GB 2Rx4 PC3L-12800R to see if it runs, but I would like for someone to help,

please let me know if there is any more information I should provide, any help is welcome.

I did not activate the hyper V role.

I also have read the entirety of the configuring memory page already

Hi,

Have you checked the QuickSpecs for this server, page# 49 onwards.
BTW, I dont see E5-2695 V2 as compatible with this server model.  Page# 2, 3

Thank You!
I work with HPE but opinions expressed here are mine.

Hello,

While that is true, the only difference I have been able to notice from Intel's website is that the CPU I have runs at a lower base clock rate and runs 15W lower. Otherwise, they are identical. So I suspect this to not be a factor in the serve not booting. Especially when it seems to be a ram issue.

Good day!

It sounds like you're dealing with some compatibility issues with the RAM modules and the server's configuration.

Here are some steps you can take to troubleshoot the problem:

>> Make sure your server's firmware and BIOS are up-to-date. Sometimes, server manufacturers release updates that improve compatibility with newer hardware.

>> Check the server's documentation (You may find here: https://support.hpe.com/) for a memory compatibility list. Servers can be very picky about the type and configuration of RAM they accept. It's possible that the server might not fully support the specific RAM modules you've purchased. You mentioned trying PC3L-12800R; this could be a good test to see if it makes a difference.

>> Ensure that both CPUs are installed correctly and that they are of the same model and revision. Mismatched CPUs can cause issues.

>> Double-check the memory slot population rules for your server model. Some servers require specific slots to be populated first or have specific rules for how memory should be distributed between CPUs.

>> Sometimes, reseating the RAM modules can help establish better connections. Turn off the server, remove and reinsert the RAM sticks carefully, and ensure they are properly seated.

>> Check if your server has diagnostic LEDs or beep codes that can provide information about the issue. These can give you more specific details about what might be wrong.

>> Mixing different types of RAM (e.g., PC3L and PC3) can sometimes cause compatibility problems. If possible, try to use identical RAM modules for all slots.

>> Test each RAM module individually in all slots to identify if any particular module or slot is causing the issue. This can help isolate the problem.

>> Some servers have memory configuration utilities that allow you to configure memory settings. Check if your server has one and configure it according to your RAM setup.

>> Review the server's error logs (if available) for any specific error messages or warnings related to memory or hardware.

If none of these steps resolve the issue, it may be worth reaching out to HPE support or the place where you purchased the RAM modules for further assistance. They may have additional insights or suggestions based on your specific server model and RAM configuration.
