if buy RAM, does part number is important? does not want to bring who desktop to shop
eg i see on kingston RAM DDR4 3200mhz
KVR32N22S6
KVR32N22S8
KCP432NS8
KCP432NS6
??

ignore this, just park a post for later use

not really sure on this.. want say.. it not important.. the mobo gt list the ram part number that compatible for it. maybe some ram can be use or just works even not listed in their supported part numbers. the qs is to what extend it able to utilized the ram performance for the part number not listed on supported ram list.

Heyyy guys,

Just built my PC recently; i7 12700F, B600M, 2x8GB DDR4 3600. https://forum.lowyat.net/topic/5339043

RAM is TeamGroup Delta RGB CL18-22-22-42 https://www.teamgroupinc.com/en/product/delta-rgb-ddr4

RAM chips are some unknown Microns (not sure what the ?? means in Thaiphoon)

Are these junk Microns?

Anyhow unfortunately I cannot get my RAM setup to its rated speed so here's the situation:

1. Setup XMP at Auto was okay and stable, but found out it was running at Gear 2.

2. Manually override G2 to G1 at Bios and restarted. It booted okay until about to login to Windows10 which it then crashes and restarted.

3. This happen repeatedly so I came back to Bios and manually downtune RAM speed to 3466.

4. Booted okay at G1 and stable but then found out it had downrate to CR2.

5. So then going back and manually set CR to 1T.

6. Right now it boots at 3466MHZ, Gear 1, CR1. Been stable running, passed Memtest5 with Extreme1@anta777, and Aida64 mem test.

But I would really want to get the full rated speed of 3600, so Im asking sifus here if any settings I could do to bump up the speed back to 3600 but stable for usage.

Aida64 results


Asrock timing config


Memtest5 Extreme1@anta777 passed

Turn off XMP, update BIOS, then use these

VDDQ TX - 1.2 to 1.35v
VCC SA or System Agent voltage - 1.35v

Turn on XMP. Set it to Gear 1.

If you want more. Bump up DRAM voltage to 1.4-1.45v and use 16-16-16-39-55. Test with it. Please also take note this is pushing the RAM.

The weekend I tried it. Set VDD IMC (did not find VDDQ TX in my bios but their voltages are the same so I assumed thats it). Did not able to change VCCSA as it is nonK 12700F.

But unfortunately it bootlooped when just about to enter Windows and it the end my OS hard crashed. Orz

Now I'm trying to see how to save my OS from a reinstall.

Yeah, have to get stable RAM settings first. Try looking for System Agent voltage.

Unfortunately SA Voltage for Alderlake nonK CPU is locked

After watching this HUB video ( https://youtu.be/OsA52DkP8WU?t=216 ) I finally given up trying to get 3600MHZ to work at Gear 1. Looks like even the pros couldnt do better than 3466MHZ.

I would move onto improving timings if I still got the stomach for it, or once I can get a scratch disk to ruin its Windows when it goes too far and doesnt work.

upgraded my PC from 8GB ram to 16GB.

How come the ram i newly bought looks so much difference than the old one? both Kingston brand.

LOL Kingston itself have different segments just for RAM

https://www.kingston.com/en/memory

What you had was office type ValueRAM and what you just bought is more gamer centric HyperX with heatsink

Icic. I searched around on Shopee I can only find the RAM I bought and it is the cheapest DDR4 2133MHz I can find.

Is the so called office type of value ram sold anywhere that I can buy at even cheaper price?

my motherboard is H110M-K. and I am using i5-7500 processor. so technically it can support up to 2400 MHz DDR4 RAM.

My existing ram is 8GB 2133MHz. if i want to upgrade to 16GB, should I buy 2400MHz instead? I know that the maximum speed supported will be 2133MHz since the old one is 2133MHz only. However, if I buy 2400MHz, it will be better if the old 2133MHz spoiled which I can just buy another 2400MHz to have higher speed rite?

do 2400MHz vs 2133MHz make noticeable difference in performance?

besides, i cannot enable XMP in the BIOS although on the spec of the motherboard stated that it supports that. why is it so?


2 x DIMM, Max. 32GB, DDR4 2400/2133 MHz Non-ECC, Un-buffered Memory *
Dual Channel Memory Architecture
Supports Intel® Extreme Memory Profile (XMP)
* Due to Intel® chipset limitation, DDR4 2400MHz memory frequency is only supported by 7th Generation Intel® processors.

Yes, physical computer shops like in lowyat usually sells them. Long ago i bought such valueram from sri computer.

Should you buy it? Only if its a few RM more than 2133 RAM. You cant use the extra headroom anyways cuz ur old one also tops at 2133MHZ and valuerams dont have XMP which is why its not function. Oso the HyperX RAM you bought has XMP the same as its JEDEC rated speed so XMP setting is moot as well.

And hoping for it to die will be a long wait as RAM are the most durable thing in a PC thats why they have lifetime warranty. If you want 2400 RAMs just get a 2pack kit (8x2) and chuck out the old one.

Will the higher speed make a difference? Only slightly in benchmarks maybe a few FPS more in games. Otherwise its not like day & nite.

is it cheaper by a lot?

thanks a lot for the explanation.

actually the price of the 2400MHz and 2133MHz is the same at rm71 for the shoppe shop i bought from.
in fact 2133MHz, 2400MHz, 2666MHz all same price at rm71 while 3200MHz is only rm1 more at rm72.

1) that's why i am kind of regret now not to buy the higher speed one. it is stated that my motherboard can support up to 2400MHz of RAM, so my question is that if I put in a 3200MHz ram, will it even recognise but work at lower speed of 2400MHz? or it will just simply not working at all?

2) understood that 2400MHz vs 2133MHz the improvement will be minor. since my old ram does not support XMP, if i buy another 2133MHz ram now that supports XMP like the new one i bought. how much performance more i can probably get by doing so?

3) yeah, you are rite, RAM hardly fail. probably my motherboard spoiled first before it failed. in fact, my motherboard was having problem just 2 weeks back which it cannot be powered on. i brought to a computer shop to fix it at the price of rm100. luckily it can be fixed, else i may need to change a new motherboard which will certainly cost much more.
so kingston RAM is actually lifetime warranty? but i suppose if kingston no longer sells my model of ram, even it has lifetime warranty, it is not going to help in this case rite? which means they will not replace a RAM for me?

4) besides, may i know if there is any other brand that is better than kingston but at similar or just slightly higher pricing also that can be considered?

I have old pc, board only max 1333mhz, i put 1600mhz it work, but still running 1333mhz
Why i got 1600mhz, because 1 stick RAM keep random BSOD, RMA i get speed upgrade

If its Lowyat its not like its difficult to find and compare urself ya know
https://www.lowyat.net/sri-hardware-pricelist/

1) Nope, XMP2.0 only has 1 rated profile so you have to manually tune to 2400MHZ. Otherwise it will work at its rated JEDEC speed of 2133 (or 2400 natively for some RAM kit)

2) As I said, JEDEC speed is ady at 2133/2400 so trying to get better RAMs is moot as their XMP speeds is the same as JEDEC. There are 2400MHZ RAM kits that does 2133 JEDEC so those will get a minor boost if run at XMP but again the difference is few FPS only.

3) Imo if you can run them at 2133 without stability issues, just keep them and be happy. Since ur mobo has such limited headroom, no point to spend much more just to chase that few percentage increase.

And if you wanna know the terms of lifetime warranty, its in the slip of paper inc in ur HyperX RAM.

4) Better is very subjective...

i bought from a shopee buyer and they said they give local warranty (1 year).
price i paid is RM65.90 including shipping with all the discounts (vouchers).
noticed that the model is no longer selling officially as it is old. but the item i received looks brand new maybe this is the old stock.

is the price above 'normal' or 'reasonable' price for the model and brand of RAM i bought?

i think i will just stick to the current setup. anyway, my PC is old already. no point to spend further $$ on it.

I upgrade to 16GB from the previous 8GB because I tot that it may help in performance but so far i realise my use case may not be able to utilise much on the extra 8GB.

but it is noticed that the shared GPU ram now shows only 8GB. could not remember the amount before i upraded to 16GB. but i guess it means the shared GPU never increase even the RAM is 16GB now. probably this is the limitation of the graphic card that it only utilises 8GB out of the available 16GB.
