A quick question about RAM memory

HWINFO64 says I have this in my puter :
samsung m3781k43cb2-ctd
DDR4-2666 / PC4-21300 DDR4 SDRAM UDIMM

and I wanna know if anyone can hopefully tell me if this will work in my puter:
TEAMGROUP Elite DDR4 8GB Single 2666MHz PC4-21300 CL19 Unbuffered Non-ECC 1.2V UDIMM 288 Pin PC Computer Desktop Memory Module Ram Upgrade - TED48G2666C1901 - (1x8GB) Single

I appreciate any help anyone provides as Techspot has helped me out in the past.

One thing to consider is whether there are any differences in the DRAM default timings, voltages, etc:

https://www.samsung.com/semiconductor/global.semi/file/resource/2018/05/DDR4_8Gb_C_die_Unbuffered_DIMM_Rev1.4_Apr.18.pdf

https://www.teamgroupinc.com/jp/catalog/act.php?act=2&index_id=72

Samsung: CL19-19-19-46 1.2V
TeamGroup: CL19-19-19-43 1.2V

The only difference, then, is the cycle row time (tRC - the last number in the list) but the motherboard will probably default to the slowest of the two. This shouldn't be a problem.

You wouldnt happen to know of any memory that would work for sure and affordable
im looking on Amazon but I cant make heads or tails out of what im seeing?

1 more question if I may would this work as well in the puter I have
Gigabyte GeForce GTX 1660 OC 6G Graphics Card, 2X Windforce Fans, 6GB 192-bit GDDR5, Gv-N1660OC-6GD Video Card

It really should work okay - the only thing that's not certain is whether the TeamGroup would be forced to run at the same tRC as the installed Samsung DIMM or the other way round. DRAM will always work on slower timings but the difference between 43 cycles and 46 cycles probably isn't big enough to cause any issues if the Samsung is forced to run at the faster rate. My gut feeling is that the BIOS will just go with the slower of the two.

You could buy a dual DIMM kit and sell the Samsung DIMM to help fund it:

If you're just using your PC for basic office work and gaming, you're not going to see any real benefit going from 8 GB single channel DRAM to 16 GB dual channel - fully CPU games/applications will show a small increase:

So im right to upgrade the memory over the video card first and then worry bout video cards?

oh sorry its mainly for gaming.

Well, upgrading memory is a lot cheaper than upgrading the graphics card :)

But for the resolutions and graphics settings that your 1660 is comfortable running at, your games aren't going to benefit from having 16 GB of RAM.

Your machine will almost certainly be fine with an extra 8GB DIMM put in it, but it's not going to make much of a difference.

Ypu wouldnt happen to know of a good affordable video card you would recommend for me would you?

I thought I might try to max out the ram to 32

If you're going to all out with the RAM, and fill all 4 DIMM slots, try to get a 2 x 16 GB kit rather than filling it up stick at a time. This is because the DIMMs in the kit will be matched, for timing and stability, by the manufacturer. The downside is that a matched kit is a little more expensive compared to buying two separate brands/models/etc.

As for replacing the video card, "affordable" means different things to different people. For example, your current GeForce GTX 1660 is about the $200-220 region and it's about as good as you're going to get, in that price range (unless you go for a second hand card). If you're going to replace it, then you should always look at going with something that will provide a meaningful increase in performance, so a 1660 Ti would be a waste of time. However, a GeForce RTX 2060 Super or a Radeon RX 5700 XT, although almost twice the price of the 1660, are substantial better graphics cards.

I was going to go with memory you linked above (Timetec 2x8gb) and buy 4x8gb or 2 of what you linked above bout $130
In my computer it says I have
[SIZE=4]NVIDIA GeForce GTX 1070 and is 8gb
the one I thought bout purchasing has only 6gb
I will keep the [/SIZE]NVIDIA GeForce GTX 1070
I didnt realize the 8 and 6 gb difference.

Ah, my apologies - I hadn't realised the 1660 was a card you were considering; as good as it is for $220, it's no faster than a 1070 (and often slower, depending on the game).

I'd go with 2 x 16 GB, rather than 4 x 8 GB, as it will boot slightly faster (there's really not much in it, though) and heat dispersion will be better too. That said, a big block of 4 DIMMs does look good!

Yes, that will work fine with your system. One quick question: do you currently overclock the 8GB RAM you have at all?
 

jerry1969

TS Enthusiast
No dont know how
just play games with what I got lol
ok im gonna hit buy
now if im right when the new memory gets here I take the 8gb out thats in there and put the 2 sticks in correct?
I think my system can only be upgraded to 32 gb ram.

Yes, that's right - just go with the 2 new DIMMs; just following the manual I linked to earlier.

Just wanted to let you know I got the 32gb ram installed and everything is registering.
However I made a horrible mistake....my video cards is only a 2 gb
Any afordable cards come to mind that would work with my puter and 1 other question......are there any programs for free that I would be able to use to see if an upgrade would work with my computer.......im always asking if this or that will work?

Good to know that that the RAM is working - welcome to the 32GB club! (y) (Y)

To answer your second question, the answer is yes, but with a caveat. Use this website:

https://pcpartpicker.com/list/

The drawback with the website is (a) it's not 100% accurate/perfect and (b) you need to know the exact brand and model of the components in your PC. You can find a summary of that information by using the free version of 3DMark:

http://store.steampowered.com/app/223850/?_ga=2.54035496.1803771759.1565420300-681822798.1565420300

It has a system scanning tool built into it, and will tell you the make/model of your CPU, GPU, and motherboard.

Edit: Here is a 3DMark Fire Strike test of mine:

https://www.3dmark.com/3dm/38396677?

This test is one of the free ones, but you can see that a little breakdown of what's in the PC.

But there's nothing wrong with asking questions here, as there always seems to be someone willing to offer an answer!

As for the graphics card, what budget do you have for a new one? There is a lot to choose from, so knowing exactly what your maximum spend is going to be, will really narrow it down.

Don't forget that TechSpot does a 'Best of...' guide for graphics cards:
