  1. Hi Nathan, I finally received my RAM from UK, and everything is fine now. Here is my last benchmark: NovaBench Score: 323 24/09/2012 01:08:53 Microsoft Windows 7 Edition Familiale Premium Intel Core2 Duo E4500 2.20GHz @ 2200 MHz Graphics Card: NVIDIA GeForce 7100 GS 3328 MB System RAM (Score: 94) - RAM Speed: 2489 MB/s CPU Tests (Score: 208) - Floating Point Operations/Second: 50669674 - Integer Operations/Second: 122690458 - MD5 Hashes Generated/Second: 697029 Graphics Tests (Score: 10) - 3D Frames Per Second: 37 Hardware Tests (Score: 11) - Primary Partition Capacity: 58 GB - Drive Write Speed: 66 MB/s Guess that was some incompatibility of some sort. Thank you for your attention. :smile:
  2. Hi Nathan, and thank you for your answer. Yes, when checked with CPU-Z, all the specs were the same (tab "SPD", and checked for the 4 slots). Then, I ran 2 tests: - first, a memory test done by windows 7: everything was OK. and then, I ran MEMTEST86+ that I have on a G-parted CD, and everything went fine. I then retried Novabench benchmark, and it went as low as 400 Mhz. But curiously, the computer is not slow. Anyway, it smelling incompatibility of some sort I guess. So I took them off from the computer, and sent them back to the seller. I have 2 other RAM modules on their way from UK, but this time, they are not new but refurbished, but are exactly the same model as I have. I will let you know if it solve the problem. Thank you for your interest in my problem! :wink:
  3. Hi to all the Novabenchers here, I have a problem concerning my RAM. I had 2 GB of Samsung RAM PC2 5300U in my computer (complete reference: 1GB 2Rx8 PC2 - 5300U - 555 - 12 - E3 M378T2953EZ3 - CE6 0720). Here is the Novabench's benchmark with those 2 GB: NovaBench Score: 331 (RAM 2 GB, Samsung) 15/09/2012 14:33:17 Microsoft Windows 7 Edition Familiale Premium Intel Core2 Duo E4500 2.20GHz @ 2200 MHz Graphics Card: NVIDIA GeForce 7100 GS 2048 MB System RAM (Score: 100) - RAM Speed: 2541 MB/s CPU Tests (Score: 211) - Floating Point Operations/Second: 50734236 - Integer Operations/Second: 126255018 - MD5 Hashes Generated/Second: 709107 Graphics Tests (Score: 10) - 3D Frames Per Second: 38 Hardware Tests (Score: 10) - Primary Partition Capacity: 58 GB - Drive Write Speed: 53 MB/s After that, I wanted to add more RAM. I saw on internet that it seems I could buy DDR2 5300, the "U" at the end of Samsung's reference (5300U) wouldn't matter. So I bought 2 GB of generic RAM (in fact, it is Crucial RAM). Here are the references: DDR2 667 Mhz / PC5300 1 GB. Here is the Novabench's benchmark ONLY with those 2 new GB (so I remove the Samsung RAM for this benchmark): NovaBench Score: 327 (RAM 2GB, generic) 15/09/2012 04:42:03 Microsoft Windows 7 Edition Familiale Premium Intel Core2 Duo E4500 2.20GHz @ 2200 MHz Graphics Card: NVIDIA GeForce 7100 GS 2048 MB System RAM (Score: 97) - RAM Speed: 1931 MB/s CPU Tests (Score: 211) - Floating Point Operations/Second: 50735644 - Integer Operations/Second: 126303410 - MD5 Hashes Generated/Second: 709234 Graphics Tests (Score: 10) - 3D Frames Per Second: 38 Hardware Tests (Score: 9) - Primary Partition Capacity: 58 GB - Drive Write Speed: 49 MB/s Not the best, but still OK. Finally, I installed all the 4GB in my computer, and now the RAM benchmark is awful: NovaBench Score: 318 (RAM 4 GB, Samsung + generic) 13/09/2012 01:23:15 Microsoft Windows 7 Edition Familiale Premium Intel Core2 Duo E4500 2.20GHz @ 2200 MHz Graphics Card: NVIDIA GeForce 7100 GS 3328 MB System RAM (Score: 85) - RAM Speed: 755 MB/s CPU Tests (Score: 212) - Floating Point Operations/Second: 50716850 - Integer Operations/Second: 127483306 - MD5 Hashes Generated/Second: 711694 Graphics Tests (Score: 10) - 3D Frames Per Second: 37 Hardware Tests (Score: 11) - Primary Partition Capacity: 58 GB - Drive Write Speed: 72 MB/s During the 3 times, my RAM worked in dual chanel (as seen in CPU-Z), and the caracteristics of both types of RAM are absolutely identical in CPU-Z (except for the manufacturer/model and the year). Curiously, Novabench only detects 3328 MB, and not 4000 MB (I'm using Windows 7 64 bits). Well, I'm a little bit lost concerning all this affair. I don't know what to think. If somebody has an opinion about what's happening that makes my RAM speed collapses as it does, I would be glad to hear it. Anyway, I thank everybody who will have a little bit of time to answer to this topic! Have a good day.
