My answer changes. It appears the i7 isn't as compatible as you claim. Part of the memory management (chip, stick support) is in the CPU so there it is. Maybe nothing is broken here. The machine works fine with the CPU it came with.
Case closed.
Hi dear fellows,
First of all, please note that I will talk about a laptop problem, not about desktop/builds. I have a laptop with a HM76 Chipset and I've upgrade from an i5 3210M to an i7 3630QM, so perfectly compatible. I also bought an additional stick of 8GB RAM with dual voltage of 1.35V and 1.5V, from Crucial (according to the information on the Crucial's website, I think they are both running at 1.5V).
It was everything OK and I was very happy with the big upgrade. However, when I decide to do a memory test with memtest86 and memtest86+ I got many errors, but just in the latest tests, and always after 1h of test (with Windows diagnostic tool I had no errors). So I did some tests with memtest86 to know which RAM stick was damaged and I came to the conclusion that both sticks are both good but Slot 1 don't. If I put any stick of RAM in the Slot 1 I have errors in memtest86 and BSoD in Prime95. If I just use the Slot 2 I have no problems. I don't know if I already had this problem in Slot 1 before the upgrade, because I never did a scan memtest86, or if by some (very strange) reason, I have damaged the motherboard/Slot 1 with this CPU and RAM upgrade.
But, what I would like to ask is if there is any problem of ignoring this damage in Slot 1 and use only the Slot 2 with the limited 8GB RAM, or if it is probable that the motherboard will show more problems/errors/damages in the future.. ?? Should I by another motherboard, or I will not have bigger problems than an unusable Slot of RAM?
Thank you in advance for your time and help,
I wish you all a great week!
Best regards.
